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.

Script Switching in Roman Egypt studies the hieroglyphic, hieratic, demotic, and Old Coptic manuscripts which evidence the conventions governing script use, the domains of writing those scripts inhabited, and the shift of scripts between those domains, to elucidate the obsolescence of those scripts from their domains during the Roman Period. Utilising macro-level frameworks from sociolinguistics, the textual culture from four sites is contextualised within the priestly communities of speech, script, and practice that produced them. Utilising micro-level frameworks from linguistics, both the scripts of the Egyptian writing system written, and the way the orthographic methods fundamental to those scripts changed, are typologised. This study also treats the way in which morphographic and alphabetic orthographies are deciphered and understood by the reading brain, and how changes in spelling over time both resulted from and responded to dimensions of orthographic depth. Through a cross-cultural consideration of script obsolescence in Mesoamerica and Mesopotamia and by analogy to language death in speech communities, a model of domain-bydomain shift and obsolescence of the scripts of the Egyptian writing system is proposed.

Petitioning Osiris re-edits, re-analyses, and re-contextualises the "Old Coptic Schmidt Papyrus" and "Curse of Artemisia" - written petitions to different manifestations of Osiris - among the Letters to Gods in Demotic, Greek, and Old Coptic from Egypt. The textual traditions of the Letters to Gods, to the Dead, and Oracle Questions which evidence that ritual tradition of petitioning deities are contextualised among contemporary textual traditions, such as Letters and Petitions to Human Recipients, and Documents of Self-Dedication, and compared to later ritual traditions such as proactive and reactive curses without and with judicial features (so-called Prayers for Justice) in Greek and Coptic from Egypt and the Eastern Mediterranean. As with all other Letters to Gods, the Old Coptic Schmidt Papyrus and Curse of Artemisia evidence not only the struggles and aspirations of their petitioners, but also the way in which they conceptualised that they could bring about desired outcomes in their lived experience by engaging divine agency through a reciprocal relationship of human-divine interaction. Petitioning Osiris therefore provides a starting point and springboard for readers interested in these, or comparable, textual and ritual traditions from the Ancient World.
