This talk stages a dialogue between two theatrical traditions at the end of the Middle Ages: the popular theater of the Arabic and Islamic world and the theater of Christian Europe. It does so through the adventures of Hasan al-Wazzan ('Leo Africanus'), a Moroccan traveler and diplomat, who was captured by Christian pirates in 1518 and spent several years in Italy as a seeming convert before returning to North Africa. The talk reflects on possible limits to cultural exchange and on the continuing vigor of alternate cultural traditions.
