John Selden's 1642 edition and translation of an extract from a chronicle by Eutychius (Said ibn Batriq), the tenth-century Melkite patriarch of Alexandria, can be considered the first Arabic book printed in England. This article examines the early reception of Selden's Eutychius in the European republic of letters, exploring the ways in which its testimony about the early Alexandrian Church contributed to scholarly debates over episcopacy against the backdrop of the English Revolution. In doing so it demonstrates how Selden's edition made Eutychius a touchstone in seventeenth-century confessional disputes over ecclesiastical history while attracting readers in England and abroad.
