"The Legacy of Demetrius is a multi-faceted jewel of historical investigation. Mikhail first gathers together and contextualizes virtually all that we know of Demetrius himself, and then draws out for us the process through which Demetrius the legend evolved. Through this complex investigation new windows are also opened onto the distinctive shape of Christianity in late antique and Islamic Egypt. Rarely does a study so well combine these different style of exploration." - Lewis Ayres, Durham University, UK"Due to [his] innovative approach and a sovereign handling of the sources, Mikhail's book is considered very successful. His deconstruction of hagiographic legends and motifs, coupled with his analysis of various editorial levels, would have to set a new standard for the study of hagiographic texts."- Daniel Vaucher, Universität Bern, Germany, Bryn Mawr Classical Review 2017
