Saint Zenobius (†417) is venerated as the first bishop of Florence. He embraced the clerical state, and rapidly rose to the position of archdeacon, when his virtues and notable powers as a preacher made him known to Saint Ambrose, at whose instance Pope Damasus I (r. 366–386) called him to Rome, and employed him in various important missions, including a legation to Constantinople. On the death of Damasus he returned to his native city, where he resumed his apostolic labours, and on the death of the bishop of that see, Zenobius was appointed to succeed him. Extraordinary miracles, including several instances of the restoration of the dead to life, are attributed to him. It is also said that after his death, a dead elm burst into life after his body touched it while being borne to the cathedral for burial.His feast day is celebrated on May 25.
