Syriac Christians Envisioning Islam

Michael Phillip Penn, whose other publication this year on Syrians encountering Islam was noted here, has another book coming out in June that I'm eagerly looking forward to reading: Envisioning Islam: Syriac Christians and the Early Muslim World (U Penn Press, 2015), 320pp.

About this book we are told:

The first Christians to encounter Islam were not Latin-speakers from the western Mediterranean or Greek-speakers from Constantinople but Mesopotamian Christians who spoke the Aramaic dialect of Syriac. Under Muslim rule from the seventh century onward, Syriac Christians wrote the most extensive descriptions extant of early Islam. Seldom translated and often omitted from modern historical reconstructions, this vast body of texts reveals a complicated and evolving range of religious and cultural exchanges that took place from the seventh to the ninth century.
The first book-length analysis of these earliest encounters, Envisioning Islam highlights the ways these neglected texts challenge the modern scholarly narrative of early Muslim conquests, rulers, and religious practice. Examining Syriac sources including letters, theological tracts, scientific treatises, and histories, Michael Philip Penn reveals a culture of substantial interreligious interaction in which the categorical boundaries between Christianity and Islam were more ambiguous than distinct. The diversity of ancient Syriac images of Islam, he demonstrates, revolutionizes our understanding of the early Islamic world and challenges widespread cultural assumptions about the history of exclusively hostile Christian-Muslim relations.
