The '''[[Aztec]] sun stone''', ([[Nahuatl language|Nahuatl]]: '''''Ollin Tonatiuh''''' "Movement of the Sun") often mistakenly called the [[Aztec calendar]] stone, is a large monolithic sculpture that was excavated in Zócalo, [[Tenochtitlan]]'s and [[Mexico City]]'s main square.

The '''Aztec sun stone''' ({{langx|es|Piedra del Sol}}) is a late post-classic [[Mexica]] sculpture housed in the [[Museo Nacional de Antropología|National Anthropology Museum]] in [[Mexico City]], and is perhaps the most famous work of [[Aztecs#Sculpture|Mexica sculpture]].<ref>{{Cite web |url=http://www.mna.inah.gob.mx/coleccion/pieza-243/ficha-basica.html |title=National Anthropology Museum, Mexico City, "Sun Stone" |access-date=2014-04-06 |archive-url=https://web.archive.org/web/20140407104143/http://www.mna.inah.gob.mx/coleccion/pieza-243/ficha-basica.html |archive-date=2014-04-07 |url-status=dead }}</ref> It measures {{convert|3.6|m|ft}} in diameter and {{convert|98|cm|in}} thick, and weighs {{cvt|24590|kg}}.<ref>Ordóñez, Esequiel (1893).

== History ==
Measuring about 12 feet in diameter and weighing 24 tons in weight, the original basalt version is presently on display at the [[National Museum of Anthropology and History]] in [[Chapultepec Park]] outside of [[Mexico City]] in North America.
The monolith was carved by the [[Mexica]] at the end of the [[Mesoamerican chronology#Postclassic Period|Mesoamer]]

Although the exact date of its creation is unknown, the name glyph of the Aztec ruler [[Moctezuma II]] in the central disc dates the monument to his reign between 1502 and 1520.<ref>{{Cite book|title=Time, History, and Belief in Aztec and Colonial Mexico|url=https://archive.org/details/timehistorybelie00hass_707|url-access=limited|last=Hassig|first=Ross|publisher=University of Texas Press|year=2001|isbn=978-0292731400|location=Austin|pages=[https://archive.org/details/timehistorybelie00hass_707/page/n66 48]–69|chapter=Reinterpreting Aztec Perspectives}}</ref> There are no clear indications about the authorship or purpose of the monolith, although there are certain references to the construction of a huge block of stone by the Mexicas in their last stage of splendor.

While it is called the Aztec Sun Stone, this sculpture did not originally come from Aztlan but was created by the [[Mexica]] people. And while it is often called the Aztec Calendar, it primarily depicts the four great disasters which led to the migration of the Mexica to [[Tenochtitlan]] (modern day Mexico City).
 
The parent rock from which it was extracted comes from the [[Xitle]] volcano, and could have been obtained from San Ángel or [[Xochimilco]].<ref name="HistoryinStone">{{cite web |url=http://www.inah.gob.mx/images/stories/Multimedia/Interactivos/monolitos/ |title=History in Stone |access-date=2018-11-27 |archive-date=2014-07-22 |archive-url=https://web.archive.org/web/20140722051124/http://www.inah.gob.mx/images/stories/Multimedia/Interactivos/monolitos/ |url-status=dead }}</ref> The geologist Ezequiel Ordóñez in 1893 determined such an origin and ruled it as [[olivine basalt]]. It was probably dragged by thousands of people from a maximum of 22 kilometers to the center of [[Tenochtitlan|Mexico-Tenochtitlan]].<ref name="HistoryinStone"/>
It also contains pictographs depicting the way the Mexica measured time, and was primarily a religious artifact.
 
After the conquest, it was transferred to the exterior of the ''[[Templo Mayor]]'', to the west of the then [[National Palace (Mexico)|Palacio Virreinal]] and the Acequia Real, where it remained uncovered, with the relief upwards for many years.<ref name="LopezLujan"/> According to Durán, [[Alonso de Montúfar]], [[Archbishop of Mexico]] from 1551 to 1572, ordered the burial of the Sun Stone so that "the memory of the ancient sacrifice that was made there would be lost".<ref name="LopezLujan"/>
The [[Aztec Calendar]] page also contains more information on how the Aztecs marked time.
 
Towards the end of the 18th century, the [[viceroy]] [[Juan Vicente de Güemes, 2nd Count of Revillagigedo|Juan Vicente de Güemes]] initiated a series of urban reforms in the capital of [[New Spain]]. One of them was the construction of new streets and the improvement of parts of the city, through the introduction of drains and sidewalks. In the case of the then so-called Plaza Mayor, sewers were built, the floor was leveled and areas were remodeled. It was [[José Damián Ortiz de Castro]], the architect overseeing public works, who reported the finding of the sun stone on 17 December 1790. The monolith was found half a yard (about 40 centimeters) under the ground surface and 60 meters to the west of the second door of the viceregal palace,<ref name="LopezLujan"/> and removed from the earth with a "real rigging with double pulley".<ref name="LopezLujan"/> [[Antonio de León y Gama]] came to the discovery site to observe and determine the origin and meaning of the monument found.<ref name="LopezLujan"/> According to [[Alfredo Chavero]],<ref name="Chavero">{{cite web |url= http://cdigital.dgb.uanl.mx/la/1080028399/1080028399.PDF|title=Calendario Azteca: un ensayo arqueológico |last=Chavero |first=Alfredo |date= 1876 |publisher=Imprenta de Jens y Zapiaine }}</ref> it was Antonio who gave it the name of [[Aztec Calendar]], believing it to be an object of public consultation. León y Gama said the following:
== Understanding the Sun Stone ==
[[Image:Calendário Asteca.jpg|right|thumb|Detailed depiction of the Aztec Sun Stone, often mistakenly called the Aztec Calendar Stone.]]
 
{{Blockquote |... On the occasion of the new paving, the floor of the Plaza being lowered, on December 17 of the same year, 1790, it was discovered only half a yard deep, and at a distance of 80 to the West from the same second door of the Royal Palace, and 37 north of the Portal of Flowers, the second Stone, by the back surface of it.| León y Gama, as cited by Chavero<ref name="Chavero"/>}}
It was believed that there were four previous iterations of the Earth to the people of Mexica, and the Sun Stone depicts each one of these iterations. Historians speculate that the Sun Stone depicts the migrations of original Native Americans, who were first forced to migrate from their prosperous lands from the North to the lands of the [[Nahuatl]], [[Chicomostoc]] and [[Aztlan]], before arriving finally to the valley where they founded [[Tenochtitlan]].
 
[[File:Aztec Solar Disk Calendar.png|thumb|Reproduction of the Aztec Sun Stone.]]
The Aztecs believed that they were living in the fifth and last creation of their world. To this end, the Aztec Sun Stone is dedicated to the [[Sun]] [[god]] [[Tonatiuh]], who was believed to have been the fifth sun god, as a means to prevent further catastrophe and end of the world by performing regular human sacrifices in his honor.
León y Gama himself interceded before the canon of the cathedral in order that the [[monolith]] found would not be buried again due to its perceived pagan origin (for which it had been buried almost two centuries before).<ref name="SculptureMexica">{{cite book |chapter=La Piedra del Sol o Calendario Azteca |title=Escultura Monumental Mexica |last=Matos Moctezuma |first=Eduardo |date=2012 |publisher=Fondo de Cultura }}</ref> León y Gama argued that in countries like [[Italy]] there was much that was invested in rescuing and publicly showcasing monuments of the past.<ref name="SculptureMexica"/> It is noteworthy that, for the spirit of the time, efforts were made to exhibit the monolith in a public place and also to promote its study.<ref name="SculptureMexica"/> León y Gama defended in his writings the artistic character of the stone, in competition with arguments of authors like [[Georges-Louis Leclerc, Comte de Buffon]], who gave lesser value to those born in the [[American continent]], including their artistic talent.<ref name="SculptureMexica"/>
 
The monolith was placed on one side of the west tower of the [[Mexico City Metropolitan Cathedral|Metropolitan Cathedral]] on 2 July 1791. There it was observed by, among others, [[Alexander von Humboldt]], who made several studies of its iconography.<ref name="LopezLujan"/> Mexican sources alleged that during the [[Mexican–American War]], soldiers of the [[United States Army]] who occupied the plaza used it for target shooting, though there is no evidence of such damage to the sculpture.<ref name="LopezLujan"/> Victorious General [[Winfield Scott]] contemplated taking it back to Washington D.C. as a war trophy, if the Mexicans did not make peace.<ref>Van Wagengen, Michael Scott. ''Remembering the Forgotten War: The Enduring Legacies of the U.S.-Mexican War''. Amherst: University of Massachusetts Press 2012, pp. 25–26</ref>
In the center of the sun stone is believed to be either the sun god [[Tonatiuh]] or the earth god [[Tlaltecuhtli]]. The central figure's tongue is shown to be a sacrificial knife, while the circles on either ends depict claws holding human hearts for sacrificial purposes.
 
In August 1885, the stone was transferred to the Monolith Gallery of the Archaeological Museum on Moneda Street, on the initiative of Jesús Sánchez, director of the same.<ref name="LopezLujan"/> Through documents from the time, it is known that popular animosity resulted from the "confinement" of a public city icon.<ref name="LopezLujan"/>
The four squares around the central deity depict the previous four suns (or worlds) that perished. On the top right square is depicted the jaguar. Moving to the left is the wind, below the wind is fiery rain and in the bottom right square is water.
 
In 1964 the stone was transferred to the [[National Museum of Anthropology (Mexico)|National Museum of Anthropology]], where the stone presides over the Mexica Hall of the museum and is inscribed in various Mexican coins.
Continuing outward from the inner circle, the next concentric circle consists of twenty squares, each naming one of the twenty different days of the Aztec month. Clockwise, these days are:
 
Before the discovery of the monolith of [[Tlaltecuhtli]], deity of the earth, with measurements being 4 by 3.57 meters high, it was thought that the sun stone was the largest Mexica monolith in dimensions.

== Physical description and iconography ==
Each Aztec year consisted of eighteen months and each month had 20 days. Five more dots called [[Nemontemi]] were added inside the circle, which depicted days for sacrifice, bringing up the total number of days to 365.
[[File:File-Monolito de la Piedra del Sol (centro).jpg|thumb|right|250px|Detail of the two innermost circles of the monolith]]
The sculpted motifs that cover the surface of the stone refer to central components of the [[Mexica]] [[cosmogony]]. The state-sponsored monument linked aspects of Aztec ideology such as the importance of violence and warfare, the cosmic cycles, and the nature of the relationship between gods and man. The Aztec elite used this relationship with the cosmos and the bloodshed often associated with it to maintain control over the population, and the sun stone was a tool in which the ideology was visually manifested.<ref>{{Cite journal|last=Brumfiel|first=Elizabeth|date=1998|title=Huitzilopochtli's Conquest: Aztec Ideology in the Archaeological Record|journal=Cambridge Archaeological Journal|volume=8|pages=3–13|doi=10.1017/s095977430000127x|s2cid=162453955 }}</ref>
[[File:Sunstone annotations.png|thumb|A diagram of the sun stone with the major symbolism labeled]]
 
=== Central disk ===
The next concentric circle on the stone contains several square sections, with each section containing five dots which are believed to probably represent weeks of five days. There are also eight angles which divide the stone into eight parts. These are believed to represent the suns rays placed in accordance to cardinal points.
In the center of the monolith is often believed to be the face of the solar deity, [[Tonatiuh]],<ref>The public description by the National Anthropology Museum assigns the face to the fire god, [[Xiuhtecuhtli]].</ref> which appears inside the glyph for "movement" ([[Nahuatl]]: ''Ōllin''), the name of the current era. Some scholars have argued that the identity of the central face is of the earth monster, [[Tlaltecuhtli]], or of a hybrid deity known as "Yohualtecuhtli" who is referred to as the "Lord of the Night". This debate on the identity of the central figure is based on representations of the deities in other works as well as the role of the sun stone in sacrificial context, which involved the actions of deities and humans to preserve the cycles of time.<ref>{{Cite journal|last=Klein|first=Cecelia F.|date=March 1972|title=The Identity of the Central Deity on the Aztec Calendar|journal=The Art Bulletin|volume=58|issue=1|pages=1–12|via=JSTOR|doi=10.1080/00043079.1976.10787237}}</ref> The central figure is shown holding a human heart in each of his clawed hands, and his tongue is represented by a stone sacrificial knife (''[[Tecpatl]]'').
 
=== Four previous suns or eras ===
On the lower portion of the stone, there are two snakes that are shown to encircle the stone and face each other. Their bodies are divided into sections which depict the symbols representing flames, elephant-trunks and jaguar limbs. These sections are believed to represent fifty-two year cycles: the Aztec century consisted of 52 years.
The four squares that surround the central deity represent the [[five suns|four previous suns]] or eras, which preceded the present era, "Four Movement" ([[Nahuatl]]: ''[[Nahui Ollin|Nahui Ōllin]]''). The Aztecs changed the order of the suns and introduced a fifth sun named "Four Movement" after they seized power over the central highlands.<ref>{{Cite book |title= The Aztec Calendar Stone |last1= Villela |first1= Khristaan |publisher= Getty Research Institute |year=2010 |location= Los Angeles |pages= 258 |chapter= The Stone of the Sun |author2= Michel Graulich }}</ref> Each era ended with the destruction of the world and humanity, which were then recreated in the next era.
* The top right square represents "Four Jaguar" ([[Nahuatl]]: ''Nahui Ōcēlotl''<nowiki/>), the day on which the first era ended, after having lasted 676 years, due to the appearance of monsters that devoured all of humanity.
* The top left square shows "Four Wind" ([[Nahuatl]]: ''Nahui Ehēcatl''<nowiki/>), the date on which, after 364 years, hurricane winds destroyed the earth, and humans were turned into monkeys.
* The bottom left square shows "Four Rain" ([[Nahuatl]]: ''Nahui Quiyahuitl''<nowiki/>). This era lasted 312 years, before being destroyed by a rain of fire, which transformed humanity into turkeys.
* The bottom right square represents "Four Water" ([[Nahuatl]]: ''Nahui Atl''<nowiki/>), an era that lasted 676 years and ended when the world was flooded and all the humans were turned into fish.
 
The duration of the ages is expressed in years, although they must be observed through the prism of Aztec time. In fact the common thread of figures 676, 364 and 312 is that they are multiples of 52, and 52 years is the duration of one Aztec "century", and that is how they can express a certain amount of Aztec centuries. Thus, 676 years are 13 Aztec centuries; 364 years are 7, and 312 years are 6 Aztec centuries.
At the top of the calendar, a square has been carved in between the tails of the large snakes. Inside the square, the date 13 [[Acatl]] has been carved. This is believed to correspond to 1479, the year in which the calendar was completed.
 
Placed among these four squares are three additional dates, "One Flint" (''Tecpatl''), "One Rain" (''Atl''), and "Seven Monkey" (''Ozomahtli''), and a ''Xiuhuitzolli'', or ruler's turquoise diadem, glyph. It has been suggested that these dates may have had both historical and cosmic significance, and that the diadem may form part of the name of the Mexica ruler, [[Moctezuma II]].<ref>Umberger, Emily. "The Structure of Aztec History". ''Archaeoastronomy'' IV, no. 4 (Oct–Dec 1981): 10–18.</ref>
At the very edge of the calendar, eight equally spaced holes appear. It is believed that the Sun Stone may also have served as a [[sundial]]; the Aztecs may have placed horizontal sticks in these holes and the shadows of the sticks would fall on the figures of the calendar, depicting and marking time.
 
=== ExternalFirst linksring ===
 
The first concentric zone or ring contains the signs corresponding to the 20 days of the 18 months and five ''[[Nēmontēmi|nemontemi]]'' of the Aztec solar calendar (Nahuatl: ''[[Xiuhpōhualli|xiuhpohualli]]''). The monument is not a functioning calendar, but instead uses the calendrical glyphs to reference the cyclical concepts of time and its relationship to the cosmic conflicts within the Aztec ideology.<ref>{{Cite journal|last=Kelin|first=Cecelia F.|date=March 1972|title=The Identity of the central Deity on the Aztec Calendar|journal=The Art Bulletin|volume=58|issue=1|pages=1–12|via=JSTOR|doi=10.1080/00043079.1976.10787237}}</ref> Beginning at the symbol just left of the large point in the previous zone, these symbols are read counterclockwise.

=== Second ring ===
The second concentric zone or ring contains several square sections, with each section containing five points. Directly above these square sections are small arches that are said to be feather ornaments. Directly above these are spurs or peaked arches that appear in groups of four.<ref name=":0" /> There are also eight angles that divide the ring into eight parts, which likely represent the sun's rays placed in the direction of the cardinal points.
 
=== Third and outermost ring ===
Two fire serpents, ''[[Xiuhcoatl]]'', take up almost this entire zone. They are characterized by the flames emerging from their bodies, the square shaped segments that make up their bodies, the points that form their tails, and their unusual heads and mouths. At the very bottom of the surface of the stone, are human heads emerging from the mouths of these serpents. Scholars have tried to identify these profiles of human heads as deities, but have not come to a consensus.<ref name=":0" /> One possible interpretation of the two serpents is that they represent two rival deities who were involved in the creation story of the fifth and current "sun", [[Quetzalcoatl|Queztalcoatl]] and [[Tezcatlipoca]]. The tongues of the serpents are touching, referencing the continuity of time and the continuous power struggle between the deities over the earthly and terrestrial worlds.<ref name=":2">{{Cite book|title=Handbook to: Life in the Aztec World|last=Aguilar-Moreno|first=Manuel|publisher=Oxford University Press|year=2006|isbn=978-0195330830|location=Oxford|pages=181–182}}</ref>
[[File:Aztec sun stone JC 03.JPG|thumb|Some of the edge region is visible in this photograph]]
In the upper part of this zone, a square carved between the tails of the serpents represents the date ''Matlactli Omey-Ácatl'' ("13-reed"). This is said to correspond to 1479, the year in which the Fifth Sun emerged in Teotihuacan during the reign of Axayácatl, and at the same time, indicating the year in which this monolithic sun stone was carved.<ref name=":0" />
 
=== Edge of stone ===
The edge of the stone measures approximately 20 cm (8 inches) and contains a band of a series of dots as well as what have been said to be flint knives. This area has been interpreted as representing a starry night sky.<ref name=":0" />

From the moment the Sun Stone was discovered in 1790, many scholars have worked at making sense of the stone's complexity. This provides a long history of over 200 years of archaeologists, scholars, and historians adding to the interpretation of the stone.<ref name="colonial_latin_america_p23">K. Mills, W. B. Taylor & S. L. Graham (eds), ''Colonial Latin America: A Documentary History'', 'The Aztec Stone of the Five Eras', p. 23</ref> Modern research continues to shed light or cast doubt on existing interpretations as discoveries such as further evidence of the stone's pigmentation.<ref>{{Cite journal|last=Solís|first=Felipe|date=2000|title=La Piedra del Sol|journal=Arqueología Mexicana|volume=VII|issue=41|pages=32–39}}</ref> As Eduardo Matos Moctezuma stated in 2004:<ref name=":0">{{Cite book|title=The Aztec calendar and other solar monuments|last=Eduardo.|first=Matos Moctezuma|date=2004|publisher=Conaculta-Instituto Nacional de Antropologia e Historia|others=Solís Olguín, Felipe R.|isbn=9680300323|location=México, D.F.|pages=13, 48–59, 68, 70, 72, 74|oclc=57716237}}</ref>
 
{{Blockquote|text=In addition to its tremendous aesthetic value, the Sun Stone abounds in symbolism and elements that continue to inspire researchers to search deeper for the meaning of this singular monument.|sign=[[Eduardo Matos Moctezuma]]|source=The Aztec Calendar and Other Solar Monuments}}
 
The earliest interpretations of the stone relate to what early scholars believed was its use for astrology, chronology, or as a sundial. In 1792, two years after the stone's unearthing, Mexican scholar [[Antonio de León y Gama]] wrote one of the first treatises on Mexican archaeology on the Aztec calendar and Coatlicue.<ref>Antonio de León y Gama: ''Descripción histórica y cronológica de las dos piedras'' [http://memory.loc.gov/service/rbc/rbc0001/2006/2006kislak2/2006kislak2.pdf León y Gama]</ref> He correctly identified that some of the [[glyphs]] on the stone are the glyphs for the days of the month.<ref name="colonial_latin_america_p23" /> [[Alexander von Humboldt]] also wanted to pass on his interpretation in 1803, after reading Leon y Gama's work. He disagreed about the material of the stone but generally agreed with Leon y Gama's interpretation. Both of these men incorrectly believed the stone to have been vertically positioned, but it was not until 1875 that [[Alfredo Chavero]] correctly wrote that the proper position for the stone was horizontal. Roberto Sieck Flandes in 1939 published a monumental study entitled ''How Was the Stone Known as the Aztec Calendar Painted?'' which gave evidence that the stone was indeed pigmented with bright blue, red, green, and yellow colors, just as many other Aztec sculptures have been found to have been as well. This work was later to be expanded by Felipe Solís and other scholars who would re-examine the idea of coloring and create updated digitized images for a better understanding of what the stone might have looked like.<ref name=":0" /> It was generally established that the four symbols included in the Ollin glyph represent the four past suns that the Mexica believed the earth had passed through.<ref>{{Cite book|title=State and Cosmos in the Art of Tenochtitlan|last=Townsend|first=Casey|publisher=Dumbarton Oaks|year=1979|location=Washington, DC}}</ref>
 
Another aspect of the stone is its religious significance. One theory is that the face at the center of the stone represents [[Tonatiuh]], the Aztec deity of the sun. It is for this reason that the stone became known as the "Sun Stone." Richard Townsend proposed a different theory, claiming that the figure at the center of the stone represents [[Tlaltecuhtli]], the Mexica earth deity who features in Mexica creation myths.<ref name="colonial_latin_america_p23" /> Modern archaeologists, such as those at the [[Museo Nacional de Antropología|National Anthropology Museum]] in Mexico City, believe it is more likely to have been used primarily as a ceremonial basin or ritual altar for [[Human sacrifice in Aztec culture|gladiatorial sacrifices]], than as an astrological or astronomical reference.<ref name="getty.edu"/>
 
Yet another characteristic of the stone is its possible geographic significance. The four points may relate to the four corners of the earth or the cardinal points. The inner circles may express space as well as time.<ref>K. Mills, W. B. Taylor & S. L. Graham (eds), ''Colonial Latin America: A Documentary History'', 'The Aztec Stone of the Five Eras', pp. 23, 25</ref>
 
Lastly, there is the political aspect of the stone. It may have been intended to show [[Tenochtitlan]] as the center of the world and therefore, as the center of authority.<ref>K. Mills, W. B. Taylor & S. L. Graham (eds), ''Colonial Latin America: A Documentary History'', 'The Aztec Stone of the Five Eras', pp. 25–26</ref> Townsend argues for this idea, claiming that the small glyphs of additional dates amongst the four previous suns—'''1 Flint''' (''Tecpatl''), '''1 Rain''' (''Atl''), and '''7 Monkey''' (''Ozomahtli'')—represent matters of historical importance to the Mexica state. He posits, for example, that 7 Monkey represents the significant day for the cult of a community within Tenochtitlan. His claim is further supported by the presence of Mexica ruler [[Moctezuma II]]'s name on the work. These elements ground the Stone's iconography in history rather than myth and the legitimacy of the state in the cosmos.<ref>{{Cite book|title=State and cosmos in the art of Tenochtitlan|last=Townsend|first=Richard Fraser|date=1997|publisher=Dumbarton Oaks, Trustees for Harvard University|isbn=9780884020837|oclc=912811300}}</ref>
 
=== Connections to Aztec ideology ===
The methods of Aztec rule were influenced by the story of their [[Mexica]] ancestry, who were migrants to the Mexican territory. The lived history was marked by violence and the conquering of native groups, and their mythic history was used to legitimize their conquests and the establishment of the capital [[Tenochtitlan]]. As the Aztecs grew in power, the state needed to find ways to maintain order and control over the conquered peoples, and they used religion and violence to accomplish the task.<ref name=":1">{{Cite book|title=The Aztecs|last=Smith|first=Michael|publisher=Wiley-Blackwell|year=2002|isbn=978-0631230168|edition=2nd|location=Hoboken}}</ref>
 
The state religion included a vast canon of deities that were involved in the constant cycles of death and rebirth. When the gods made the sun and the earth, they sacrificed themselves in order for the cycles of the sun to continue, and therefore for life to continue. Because the gods sacrificed themselves for humanity, humans had an understanding that they should sacrifice themselves to the gods in return. The Sun Stone's discovery near the [[Templo Mayor]] in the capital connects it to sacred rituals such as the [[New Fire ceremony|New Fire]] ceremony, which was conducted to ensure the earth's survival for another 52-year cycle, and human heart sacrifice played an important role in preserving these cosmic cycles.<ref name=":1" /> Human sacrifice was not only used in religious context; additionally, sacrifice was used as a military tactic to frighten Aztec enemies and remind those already under their control what might happen if they opposed the Empire. The state was then exploiting the sacredness of the practice to serve its own ideological intentions. The Sun Stone served as a visual reminder of the Empire's strength as a monumental object in the heart of the city and as a ritualistic object used in relation to the cosmic cycles and terrestrial power struggles.<ref>{{Cite book|title=Aztec Imperial Strategies|last=Umberger|first=Emily|publisher=Dumbarton Oaks|year=1996|isbn=978-0884022114|editor-last=Hodge|editor-first=Mary G.|location=Washington|pages=85–106|chapter=Art and Imperial Strategy in Tenochtitlan}}</ref>
 
== Modern use ==
[[File:Aztec calendar on Amate.jpg|thumb|Mexican [[Amate]] paper craft on Aztec sun stone]]
 
The sun stone image is displayed on the obverse the Mexican 20 Peso gold coin, which has a gold content of {{convert|15|g|ozt|4|abbr=off|lk=out}} and was minted from 1917 to 1921 and restruck with the date 1959 from the mid-1940s to the late 1970s. Different parts of the sun stone are represented on the current Mexican coins, with each denomination having a different section.
 
Currently, the image is present in the 10 Peso coin as part of the New Peso coin family started in 1992 having .925 silver centers and aluminum bronze rings changing in 1996 where new coins were introduced with base metal replacing the silver center.
 
The sun stone image also has been adopted by modern Mexican and Mexican American/Chicano culture figures, and is used in folk art and as a symbol of cultural identity.<ref>{{Cite book | url=https://books.google.com/books?id=aIB86sT9ItwC&q=%22aztec+calendar+stone%22+%22mexican+culture%22&pg=PA73 |title = Walls of Empowerment: Chicana/O Indigenist Murals of California|isbn = 9780292793934|last1 = Latorre|first1 = Guisela|date = December 2008}}</ref>
 
In 1996, sportswear manufacturer ABA Sport in partnership with the [[Mexico national football team]], employed a depiction of the sun stone image on its home, away and third match kits, with each individual shirt being assigned the green (home), white (away) and red (third) colors of the [[Flag of Mexico|Mexican flag]] respectively. The kit was featured until the [[1998 FIFA World Cup|1998 World Cup]] in which the Mexican side impressed the world with satisfying results.
 
[[Elvis Presley]] had a jumpsuit made with the Aztec Sun Stone which he used in the last years of his concerts and used it in his Elvis in Concert TV performance in June 19-21, 1977 and in his last live performance on stage on June 26, 1977. The suit is commonly referred to as the Mexican Sundial suit.
 
=== Impact of Spanish Colonization ===
After the conquest of the Aztec Empire by the Spanish in 1521 and the subsequent colonization of the territory, the prominence of the Mesoamerican empire was placed under harsh scrutiny by the Spanish. The rationale behind the bloodshed and sacrifice conducted by the Aztec was supported by religious and militant purposes, but the Spanish were horrified by what they saw, and the published accounts twisted the perception of the Aztecs into bloodthirsty, barbaric, and inferior people.<ref>{{Cite book|title=The Aztec World|last1=Austin|first1=Alfredo Lopéz|last2=Luján|first2=Leonardo López|publisher=Abrams|year=2008|isbn=978-0810972780|editor-last=Brumfiel|editor-first=Elizabeth M.|location=New York|pages=[https://archive.org/details/aztecworld0000unse/page/137 137–152]|chapter=Aztec Human Sacrifice|editor-last2=Feinman|editor-first2=Gary M.|chapter-url-access=registration|chapter-url=https://archive.org/details/aztecworld0000unse|url=https://archive.org/details/aztecworld0000unse/page/137}}</ref> The words and actions of the Spanish, such as the destruction, removal, or burial of Aztec objects like the Sun Stone supported this message of inferiority, which still has an impact today. The Aztec capital of [[Tenochtitlan]] was covered by the construction of Mexico City, and the monument was lost for centuries until it was unearthed in 1790.<ref name=":2" /> The reemergence of the Sun Stone sparked a renewed interest in Aztec culture, but since the Western culture now had hundreds of years of influence over the Mexican landscape, the public display of the monument next to the city's main cathedral sparked controversy. Although the object was being publicly honored, placing it in the shadow of a Catholic institution for nearly a century sent a message to some people that the Spanish would continue to dominate over the remnants of Aztec culture.<ref>{{Cite journal|last1=Brumfiel|first1=Elizabeth M.|last2=Millhauser|first2=John K.|date=2014|title=Representing Tenochtitlan: Understanding Urban Life by Collecting Material Culture|journal=Museum Anthropology|volume=37|issue=1|pages=6–16|doi=10.1111/muan.12046}}</ref>
 
Another debate sparked by the influence of the Western perspective over non-Western cultures surrounds the study and presentation of cultural objects as art objects. Carolyn Dean, a scholar of pre-Hispanic and Spanish colonial culture discusses the concept of “art by appropriation,” which displays and discusses cultural objects within the Western understanding of art. Claiming something as art often elevates the object in the viewer's mind, but then the object is only valued for its aesthetic purposes, and its historical and cultural importance is depleted.<ref name=":3">{{Cite journal|last=Dean|first=Carolyn|date=Summer 2006|title=The Trouble with (The Term) Art|journal=Art Journal|volume=65|issue=2|pages=24–32|doi=10.2307/20068464|jstor=20068464}}</ref> The Sun Stone was not made as an art object; it was a tool of the Aztec Empire used in ritual practices and as a political tool. By referring to it as a "sculpture"<ref name=":3" /> and by displaying it vertically on the wall instead of placed horizontally how it was originally used,<ref name=":2" /> the monument is defined within the Western perspective and therefore loses its cultural significance. The current display and discussion surrounding the Sun Stone is part of a greater debate on how to [[Indigenous decolonization|decolonize]] non-Western material culture.
 
==Other sun stones==
There are several other known monuments and sculptures that bear similar inscriptions. Most of them were found underneath the center of Mexico City, while others are of unknown origin. Many fall under a category known as [[temalacatl]], large stones built for ritual combat and sacrifice. Matos Moctezuma has proposed that the Aztec Sun Stone might also be one of these.<ref name="Escultura1">{{cite book|last=Matos Moctezuma|first=Eduardo|title=Escultura monumental mexica|year=2012|publisher=[[Fondo de Cultura Económica]]|location=México|isbn=9786071609328|chapter=La Piedra de Tízoc y la del Antiguo Arzobispado}}</ref>
 
===Temalacatls===
[[File:PSM V31 D091 Sacrificial stone or cuauhxicalli of tizoc.jpg|thumb|left|Sacrificial stone or Cuauhxicalli of Tizoc]]
The [[Stone of Tizoc]]'s upward-facing side contains a calendrical depiction similar to that of the subject of this page. Many of the formal elements are the same, although the five glyphs at the corners and center are not present. The tips of the compass here extend to the edge of the sculpture. The Stone of Tizoc is currently located in the [[National Anthropology Museum]] in the same gallery as the Aztec Sun Stone.
 
The [[Stone of Motecuhzoma I]] is a massive object approximately 12 feet in diameter and 3 feet high with the 8 pointed compass iconography. The center depicts the sun deity [[Tonatiuh]] with the tongue sticking out.<ref name="Brittany"/>
 
The [[Philadelphia Museum of Art]] has another.<ref>{{Cite web|url=http://www.philamuseum.org/collections/permanent/51311.html|title = Calendar Stone}}</ref> This one is much smaller, but still bears the calendar iconography and is listed in their catalog as "Calendar Stone". The side surface is split into two bands, the lower of which represents Venus with knives for eyes; the upper band has two rows of ''citlallo'' star icons.<ref name="Brittany"/>
 
A similar object is on display at the [[Yale University Art Gallery]], on loan from the [[Peabody Museum of Natural History]].<ref>{{Cite web |url=http://b01.deliver.odai.yale.edu/03/6b/036bd439-4bb3-479d-b746-3a9fe80a3df9/ANT019231-large.jpg |title=Archived copy |access-date=2018-11-05 |archive-date=2020-07-26 |archive-url=https://web.archive.org/web/20200726142625/http://b01.deliver.odai.yale.edu/03/6b/036bd439-4bb3-479d-b746-3a9fe80a3df9/ANT019231-large.jpg |url-status=dead }}</ref><ref>Peabody Museum http://collections.peabody.yale.edu/search/Record/YPM-ANT-019231</ref> The sculpture, officially known as Aztec Calendar Stone in the museum catalog but called ''Altar of the Five Cosmogonic Eras'',<ref name="Brittany"/> bears similar hieroglyphic inscriptions around the central compass motif but is distinct in that it is a rectangular prism instead of cylindrical shape, allowing the artists to add the symbols of the four previous suns at the corners.<ref name="Brittany"/> It bears some similarities to the Coronation Stone of Moctezuma II, listed in the next section.
 
===Calendar iconography in other objects===
The ''Coronation Stone of [[Moctezuma II]]'' (also known as the ''Stone of the Five Suns'') is a sculpture measuring 55.9 x 66 x 22.9&nbsp;cm (22 x 26 x 9 in<ref name="AIC">Art Institute of Chicago https://www.artic.edu/artworks/75644/coronation-stone-of-motecuhzoma-ii-stone-of-the-five-suns</ref>), currently in the possession of the [[Art Institute of Chicago]]. It bears similar hieroglyphic inscriptions to the Aztec Sun Stone, with 4-Movement at the center surrounded by 4-Jaguar, 4-Wind, 4-Rain, and 4-Water, all of which represent one of the five suns, or "cosmic eras". The year sign 11-Reed in the lower middle places the creation of this sculpture in 1503, the year of Motecuhzoma II's coronation, while 1-Crocodile, the day in the upper middle, may indicate the day of the ceremony.<ref name="AIC" /> The date glyph 1-Rabbit on the back of the sculpture (not visible in the image to the right) orients Motecuhzoma II in the cosmic cycle because that date represents "the beginning of things in the distant mythological past."<ref name="AIC" />
 
The ''[[Teocalli of the Sacred War|Throne of Montezuma]]'' uses the same cardinal point iconography<ref name="AncientEU">{{Cite encyclopedia | url=https://www.worldhistory.org/article/648/throne-of-montezuma/ | encyclopedia=[[World History Encyclopedia]] |title = Throne of Montezuma}}</ref> as part of a larger whole. The monument is on display at the [[National Museum of Anthropology]] alongside the Aztec Sun Stone and the Stone of Tizoc. The monument was discovered in 1831 underneath the [[National Palace (Mexico)|National Palace]]<ref>{{Cite web | url=https://mesoamericanonlinemuseum.weebly.com/moctezumas-throne.html | title=Moctezuma's Throne}}</ref> in [[Mexico City]] and is approximately 1 meter square at the base and 1.23 meters tall.<ref name="AncientEU" /> It is carved in a temple shape, and the year at the top, 2-House, refers to the traditional founding of [[Tenochtitlan]] in 1325 CE.<ref name="AncientEU" />
 
The compass motif with ''Ollin'' can be found in stone altars built for the [[New Fire ceremony]].<ref name="Brittany">Matos Moctezuma, ''The Aztec Calendar and other Solar Monuments''</ref> Another object, the Ceremonial Seat of Fire which belongs to the [[Santa Cecilia Acatitlan#Museum|Eusebio Davalos Hurtado Museum of Mexica Sculpture]],<ref name="Brittany"/> is visually similar but omits the central ''Ollin'' image in favor of the [[Sun]].
 
The [[British Museum]] possesses a [[cuauhxicalli]] which may depict the tension between two opposites, the power of the sun (represented by the solar face) and the power of the moon (represented with lunar iconography on the rear of the object). This would be a parallel to the [[Templo Mayor]] with its depictions of [[Huitzilopochtli]] (as one of the two deities of the temple) and the large monument to [[Coyolxauhqui]].<ref name="Brittany"/>
