The Two Firmins of Amiens
The hagiographical record of Amiens names two bishops called Firmin and does not preserve a single, undisputed account of either. The first, kept on September 25, is presented as the founding bishop of the see: a Spaniard from Pamplona, converted by Honestus the disciple of Saturninus of Toulouse, consecrated by Honoratus who succeeded Saturninus, and an active missionary across Gaul before he made Amiens his seat. He is said to have suffered martyrdom by beheading during the persecutions, traditionally placed in the reigns of Maximian and Diocletian.
The second Firmin, kept on September 1 and identified in this repository as the third bishop, is described as the son of Faustinian, a man of rank baptized by the first Firmin. According to his life he ruled the see for some forty years and was a tireless preacher in the territory of Amiens. Several sources name him a confessor who died in peace rather than a martyr; the repository, following the martyrology tradition that does not separate the two, numbers him among the hieromartyrs. No written documentation of the earliest Firmin survives from before the eighth century, and modern scholarship treats the details of both accounts with caution.
