Long before the Eastern world was discovered by the Western world, the Aztecs sacrificed people to their gods. During the changing of the seasons, the Aztecs thanked their God, Tezcatlipoca. The time of Toxcatl was a great festival and the Aztecs transformed a captive warrior into Tezcatlipoca for an entire year. The Florentine Codex was written decades after the Spanish conquest, by the Spanish priest Bernardino de Sahagun. The Aztec boys were the main writers of the Tezcatlipoca Festival. Aztec boys were trained by Franciscan missionaries to adapt Spanish phonetics and the Latin alphabet to Nahuatl. Bernardino de Sahagun had the writings of the Aztec boys translated so that the Spanish people could understand the life and history of the Aztec people. The Aztecs took a warrior captive and transformed him into the god Tezcatlipoca for an entire year. The ritual began by selecting one man in ten to become Tezcatlipoca. The selection period was to ensure that the chosen man should have a lean body. The man had to have a perfect body, there should be no defects or marks on his body. Man must learn to play the flute, smell the flowers and smoke the pipe. No one wanted to see the fat man, yet if he gained weight the Aztecs would pickle him until his body became as thin as Tezcatlipoca. The captive warrior lived as Tezcatlipoca for a year. He played the flute and was Tezcatlipoca every day of the year. The captive warrior had eight followers. Four of the eight men had haircuts like no other in Aztec culture. The four officers had spiky haircuts in the front. The Montezumas loved the captive warrior because he personified their God, Tezcatlipoca. The Aztec people brought gifts to the double in respect of Tezcatlipoca. The captive warrior dressed in great detail to impersonate Tezcatlipoca. The impersonator wore a popcorn flower crown, a shell necklace, white shell ornaments on his chest, and curved golden shell pendants hanging from his ear. The impersonator had a thin, drooping lip made of snail shell, and a string bag called a hyptoxin hung down its back. On his upper arms he wore gold bracelets and on his wrist he wore turquoise bracelets that covered his forearm. When the imitator's year was almost up, he married a woman during the period of Uey tocoztli.
