Abstract: Travel between the vying reliquary sites of St. Thomas Apostle in Chennai, India and Ortona, Italy, ruptured narrative continuity in the formation of his European cult while simultaneously fostering a thriving Indian culture of ‘Thomas Christianity.’ The arrival of missionaries and merchants from Italy and Portugal during the sixteenth and seventeenth centuries further complicated Thomas Christianity and resulted in the production of objects that merge Christian and Hindu iconographies in ways that are here elucidated for the first time. This talk thus sheds light on a little-studied chapter in the history of cultic devotion outside the conventional geographic parameters of the Renaissance and suggests an important instance of transcultural exchange during the early modern period.
