Tōnatiuh

In Mesoamerican culture, Tonatiuh (Nahuatl: Tōnatiuh [toːˈnatiʍ] "Movement of the Sun") is an Aztec sun deity of the daytime sky who rules the cardinal direction of east. According to Aztec Mythology, Tonatiuh was known as "The Fifth Sun" and was given a calendar name of naui olin, which means "4 Movement". Represented as a fierce and warlike god, he is first seen in Early Postclassic art of the Pre-Columbian civilization known as the Toltec. Tonatiuh's symbolic association with the eagle alludes to the Aztec belief of his journey as the present sun, travelling across the sky each day, where he descended in the west and ascended in the east. It was thought that his journey was sustained by the daily sacrifice of humans. His Nahuatl name can also be translated to "He Who Goes Forth Shining" or "He Who Makes The Day." Tonatiuh was thought to be the central deity on the Aztec calendar stone but is no longer identified as such. In Toltec culture, Tonatiuh is often associated with Quetzalcoatl in his manifestation as the morning star aspect of the planet Venus.
There are several versions of Tonatiuh's birth as a sun deity in the Aztec creation myth. The Aztecs (also known as the Mexica) believed in a number of sun gods. According to their mythology, Earth and its beings had been created five times in five cosmic eras and were ruled by five different sun gods. When each era or eon had ended and the sun god and its beings had been destroyed, the gods were to choose a new sun God. The four suns that preceded Tonatiuh were called "4 Jaguar", "4 Wind", "4 Water", and "4 Rain." Each of the four eras and its beings had been destroyed by an element simultaneously named after its sun god: the beings in 4 Jaguar (giants) were consumed by jaguars; the beings in 4 Wind (monkeys) were destroyed by great winds; the beings in 4 Water were consumed by water; the being in 4 Rain (turkeys) were killed by rains of fire. The first two eras lasted for 676 years, while the third era lasted for 364 years.
Tonatiuh's era was known as "the fifth age". In a myth called "The Primal Sun Myth", Tonatiuh's appearance as the fifth and final sun took place in the Pre-Columbian Mesoamerican city of Teotihuacan. According to the myth, in order for Tonatiuh to rise a substantial sacrifice had to be made. Despite the voluntary self-sacrifices from the Aztec gods Nanahuatl (or Nanahuatzin), a deformed and pimpled deity, and Teucciztecatl, Tonatiuh refused to rise and did not ascend until the canine god Xolotl sacrificed himself. In this particular account, it is said that it was the bravery of Nanahuatl that resulted in Tonatiuh's rise and that Teucciztecatl became the moon because of his hesitation before sacrificing himself.
Various accounts of the creation myth portray different narratives. According to an account by Franciscan missionary Bernardino de Sahagún, following the sacrifices of Nanahuatl and Teucciztecatl in a great fire, Tonatiuh rose weakly and did not move until the wind god Ehecatl (also known as Quetzalcoatl or called Ehecatl-Quetzalcoatl) executed Xolotl and blew Tonatiuh into motion. The telling of this version of the creation of the fifth sun was captured in a text that read:
It is also suggested that Tonatiuh is the transfigured version of Nanahuatl. In his recorded writings of the fifth sun's creation, Bernardino de Sahagún mentions that the gods were waiting for Nanahuatl to appear as the sun:
Early Pre-Columbian scholars have long identified Tonatiuh as the central deity of the Aztec calendar stone. Various scholarships, however, believe the face at the centre of the stone to be that of the earth monster Tlaltecuhtli. Tlaltecuhtli is often depicted in Aztec art with an open mouth and a sacrificial knife known as a "flint" representing a tongue. While the inner ring of the stone contains the glyph "4 Movement", it is flanked by four square compartments. These compartments and their glyphs are believed to represent the four cosmic eras prior to Tonatiuh as the fifth sun and the documentation of when each era was destroyed. Some scholars maintain the view that Tlaltecuhtli signifies the destruction of the present or fifth era by earthquakes, a view relevant to the same Aztec belief.
The iconography of Tonatiuh's physical appearance provides a visual explanation of his role as a sun deity. In certain depictions, Tonatiuh is painted in the colour red and is seen wearing an eagle feather headdress, holding a shield that could be a solar disc. Tonatiuh's connection to the sun relates to the belief that the eagle is a reference to the ascending and descending eagle talons, a visual metaphor for capturing the heart or life force of a person. This particular form of symbolism points to ritual of human sacrifice, which was associated with Tonatiuh and his devouring of the hearts of victims.
During the Spanish Conquest in the sixteenth Century, the Aztecs referred to the Spanish explorer and conquistador Pedro de Alvarado as Tonatiuh. Alvarado was said to be violent and aggressive and had a red beard, reminding them of their sun-god warrior (often painted red) Tonatiuh. In a translation of his writings, the Spanish conquistador Bernal Díaz del Castillo speaks of the Aztec's reference to Alvarado as "the Sun". Castillo describes Alvarado and Hernán Cortés meeting the Aztec ruler, Moctezuma II and being accompanied by his men, an encounter which includes a description of Alvarado's features:
