Florentius of Vienne

Saint Florentius was bishop of Vienne in Gaul at the end of the fourth century, attested by his presence at the Council of Valence in 374. He is commemorated locally on 3 January, in the Catholic Church.

The Chronicle of Archbishop Ado of Vienne (799 to 875) calls him Florent or Florentinus and gives another dating: according to it he lived in the previous century, in the time of the emperors Volusianus (251 to 253) and Gallienus (253 to 260), as the eighth bishop of Vienne, and died a martyr, in exile. The two datings do not agree, so his time remains uncertain.

He lived before the separation of the Churches, and so he is venerated as a saint of the undivided Church.
