This book is a re-edition and detailed study of a parchment codex from Egypt of the fourth century CE with Greek and Coptic recipes for healing through magic and pharmacology (Ann Arbor, University of Michigan Library Ms. 136). A text and annotated translation were published in a brief journal article by William H. Worrell in 1935, but the codex has been understudied since then. This new edition offers advances in readings and interpretation, a thorough philological commentary, and accompanying studies on the ritual and medical traditions to which the codex belongs and its position in the linguistic landscape of Egypt. The recipes comprise magical rituals for healing and broader personal advancement, pharmacological and related medical recipes, and advice for the management of a household. Traditional Egyptian religion and ritual are illustrated in interaction with medical practices of Hellenic culture more recently introduced to Egypt, and the archaic, even poetic language of some of the Coptic invocations featuring the Egyptian gods Amun and Thoth share pages with an incantation constructed from the verses of Homer.
