It is also possible that the term "Baphomet" originates from Byzantine Greek. Since the Crusaders had their first direct exposure to exotic Greek culture during the time of the First Crusade, bringing back with them stories and strange terms from the East, it is possible that the word was adapted from the Greek name of Muhammad, Μωάμεθ (Mahomet), who was at times referred to as "devilish" in near-contemporary sources such as Constantine VII's "De Administrando Imperio". It is also possible it was a fanciful name developed by Byzantine mysticism which then made its way into common speech of the time. There are contemporary metaphysical writings of the era on demons, an example being Michael Psellos' "De Operatione Daemonum". Taking this train of thought, it is not out of the question to suppose "Baphomet" was either a correct hearing of βάφω ("painted/dyed"), possibly βάφωμαι ("I am painted/dyed"), or a corruption of a phrase (or perhaps an actual demon's name) involving Greek term βαθύ ("deep").
