Tenoch is the person, whether real or mythological, for whom the Aztec city of Tenochtitlan is named. But who Tenoch was, is a bit of a mystery.
He appears frequently in many of the codices, or ancient documents, preserved from before and after the Conquest. Tenoch is recognizable by his name glyph, a rock with a cactus growing on it and he appears in Mendoza, Aubin and Azcatitlan codices. Tenoch is mentioned in several post-conquest written historic documents. He shares his name glyph with the city of Tenochtitlan.
