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.

Despite their centrality to the history of Christianity in the East, Syriac Christians have generally been excluded from modern accounts of the faith. Originating from Mesopotamia, Syriac Christians quickly spread across Eurasia, from Turkey to China, developing a distinctive and influential form of Christianity that connected empires. These early Christians wrote in the language of Syriac, the lingua franca of the late ancient Middle East, and a dialect of Aramaic, the language of Jesus. Collecting key foundational Syriac texts from the second to the fourteenth centuries, this anthology provides unique access to one of the most intriguing, but least known, branches of the Christian tradition.

The first Christians to meet Muslims were not Latin-speaking Christians from the western Mediterranean or Greek-speaking Christians from Constantinople but rather Christians from northern Mesopotamia who spoke the Aramaic dialect of Syriac. Living under Muslim rule from the seventh century to the present, Syriac Christians wrote the first and most extensive accounts of Islam, describing a complicated set of religious and cultural exchanges not reducible to the solely antagonistic. Through its critical introductions and new translations of this invaluable historical material, When Christians First Met Muslims allows scholars, students, and the general public to explore the earliest interactions between what eventually became the world's two largest religions, shedding new light on Islamic history and Christian-Muslim relations.
