Pope Fabian
It was an early tradition of the Church that under the co-Emperors Decius and Herennius Etruscus (251 AD), Pope Fabian sent out seven bishops from Rome to Gaul, to preach the Gospel: Gatien to Tours, Trophimus to Arles, Paul to Narbonne, Saturninus to Toulouse, Denis to Paris, Austromoine to Clermont, and Martial to Limoges.
