The Colliget of Averroes and the Theizir of Avenzoar, Venice 1542

A Venetian folio of 1542 that prints, as one book, the medical encyclopaedia of Ibn Rushd of Cordoba and the therapeutic manual of Ibn Zuhr of Seville — the two Andalusi physicians Latin Europe read together for four centuries. The Colliget's own prologue says who commissioned it, what it was for, and where its author claimed nothing new. A Renaissance editor added the marginal index and the doubts. It is the transmission, not the Arabic text, that this volume witnesses.
