Book excerpt: Current questions on whether Hellenistic Egypt should be understood in terms of colonialism and imperialism, multicultural separatism, or integration and syncretism have never been closely studied in the context of healing. Examing all forms of healing within the specific socioeconomic and environmental constraints of the Ptolemies’ Egypt, this book explores how linguistic, cultural and ethnic affiliations and interactions were expressed in the medical domain. Topics include the environmental and demographic background, perceptions of Greek and Egyptian medicine, the intersection between religion and healing, interactions on the theoretical and textual plane, diagnosis, prognosis and therapeutics in practice, and the range of medical practitioners. The book concludes with a case study of medicine in Ptolemaic Alexandria.
