But to the Aztecs the most important and emotive sacrifice was that of a young Aztec. This was accomplished by recruiting a handsome young volunteer and letting him live a luxurious life for a year. This youth would represent Tezcalipoca on earth; he would also get four beautiful women as his companions until the day came for him to die. He would continually go through the streets of the city playing his flute. On the appointed day of the sacrifice, the Aztecs would hold a feast in Tezcatlipoca’s honor. Then, the youth would climb the pyramid, break his flute and surrender to the priest who would sacrifice him. This was one of the more solemn festivities of the Aztec. Sahagun compared it to the Christian Easter.
