Leucius of Brindisi was a 2nd-century missionary and bishop originally from Alexandria. Born Eupressius, he entered monastic life after his mother's death and later changed his name following a vision. He traveled from Egypt to the Italian port of Brindisi to spread the Christian faith among the local pagan population. He is credited with establishing the Diocese of Brindisi and serving as its inaugural bishop. Tradition holds that he died as a martyr in the year 180.
