Yopoch was the human image, the ixiptla, of the god Huitzilopochtli. He lived for a year as the representative of the god. At the end of the year, he was brought in procession, wearing the costume of the god, to be bathed at midnight. The Nahuatl elders remembered the procession winding through the city, with a dancer called the Master of Youths of Huitznahuac leading the way. All the Masters of Youths from the telpochcalli, the young men's houses, went in the procession, followed by the young warriors and the eagle warriors. They led the procession holding burning torches for light and playing flutes, until they arrived at the Mist House, Ayauhcalco, where the images of Huitzilopochtli were bathed. Then they took the bathed image to Itepeyoc and set it in place again.
