Mexico Tenochtitlan (place of tunas on stone / the tunas are fruit which gives the nopal), was founded on a small island in the middle of a lake where in 1325 fearsomeAztec ancestors saw an eagle on a cactus, or nopal, eating a snake; scene we see depicted in the center of the Mexican flag. Finally the Aztecs found the site indicated somewhere inLake Texcoco and there founded the city. This island was where today is the center of the city. According to tradition calendar and Chronicles, these events occurred the July 18, 1318,according the codices Cuahuitlán and Vatican, and in 1325 according to Codex Mendoza. Later the Aztecs built in the place their pyramids.
The legendary tradition of the Nahua peoplesexplains that these people made a pregrinación from their place of origin, called Aztlán until what would later become Tenochtitlan, and that this pilgrimage of the nahuas-aztecas lastedfor 165 years, up to find the desired place. According to their legends their god Huitzilopochtli ('sinister Hummingbird'), had promised them that they would be a lake with an islet,which would have a rock and the rock a nopal, and on the nopal Eagle devouring a snake.
Etymologically Tenochtitlan literally means 'place of tunas on stone', the tunas are fruitwhich gives the nopal. Morphologically in Nahuatl you-nōch-ti-tlān derived from the words you (tl) 'stone', and nōch (tli) (tuna), which integrated a - ti (estativo) and - tlān ' (of), orplace where abounds something 'builds the word' tunal '. As illustrated the Codex Borgia, the word 'stone' in this case means 'heart of the Earth', since the shape that representsresembles a double human heart. The nopal, from which arise the tunas, arises directly from the goddess of the Earth. This representation provides the divine meaning the original stone.
