Zenobius of Florence was a 4th-century bishop and the first to hold the see of Florence. Born into a noble Florentine family, he was initially raised in a pagan household before converting his parents to Christianity. Following his ordination, he served in Rome under Pope Damasus I, performing various diplomatic and religious missions. He eventually returned to his home city to serve as bishop, where he worked to spread the faith and oppose Arianism. He is recognized as a saint and wonderworker in both Catholic and Orthodox traditions.
