In this paper I will examine the nature of the relationship between Hippocratic medical concepts and the practices of healing sanctuaries within Attica. I will consider the evolution of medical practice in a religious context to the time of Hippocratic medicine, the parallel floruit of Hippocratic practice and healing cults, and the relations between religious and rational medicine in their relative contexts: the temple and the city up to the Roman period. We will reassess the nature of the developing relationship between Hippocratic and religious medical practises, with particular focus on the presence of medical doctors within the healing sanctuaries.
