Magical texts are written documents which show or refer to knowledge of ancient practices of magic. Texts which are using magic might also be described as "texts of ritual power". Scholars and historians are aware that many texts of magic were written during antiquity, of which relatively few though are extant as a result of destruction of material. Emperor Augustus suppressed material by ordering the burning of 2000 scrolls (ordered during 13 B.C.E. ), authorities of Christianity pursued a frequent destruction of material pertaining to magic during at least the early centuries of Christianity (Betz 1996). Alternatively the converted Christians of the Acts of the Apostles Chapter 19 verses 17-20 of the Bible, burned their own books, of presumably writings of magic, upon becoming Christians.
