Hiob Ludolf (1624-1704) and Johann Michael Wansleben (1635-1679), the master and his erstwhile student could not be more different. Ludolf was a celebrated member of the Republic of Letters and the towering authority on Ethiopian studies. Wansleben, himself a brilliant scholar and, unlike Ludolf, a seasoned traveller in the Middle East, converted to Catholicism and eventually died impoverished and marginalized. Both stood at the centre of the burgeoning study of Ethiopia and spent a formative part of their career in middle sized Duchy of Saxe-Gotha which for several years played a pivotal role in Ethiopian-European encounters. This volume offers in-depth studies of the remarkable life and work of these two scholars in a broader intellectual, political, and confessional context.
