Carl Ernst has devoted his academic life to translating Islam, linguistically and culturally. From his first book, Words of Ecstasy in Sufism (1985), to his forthcoming book, co-edited with Fabrizio Speziale, Perso-Indica: An Analytical Survey of Persian Works on Indian Learned Traditions (online edition), he has focused on how Islamic concepts have traveled across time and space. This conference, organized around themes in Islamic studies that Ernst’s work has addressed, evokes and expands on the major contributions of this fertile, creative translator of texts, ideas, and traditions within the orb of Islam.
