The present book reveals the riches of the earliest known astrological autobiography, authored by Henry Bate of Mechelen (1246–after 1310). Exploiting all resources of contemporary astrological science, Bate conducts in his Nativitas a profound self-analysis, revealing the peculiarities of his character and personality at a crucial moment of his life (1280). The result is an extraordinarily detailed and penetrating attempt to decode the fate of one’s own life and its idiosyncrasies. The Astrological Autobiography of a Medieval Philosopher offers the first critical edition of Bate’s Nativitas. An extensive introduction presents Bate’s life and work and sheds new light on the reception and use of Greek, Latin, Arabic, and Hebrew texts among scholars in Paris at the end of the 13th century. The book thus provides a major new resource for scholars working on medieval science, autobiography, and notions of personhood and individuality.
