Austremonius (or Stremonius), St.
apostle, and first bishop of Auvergne, was one of the seven illustrious missionaries sent into Gaul by the pope about the middle of the 3d century (A.D. 250, according to the Hist. of the Martyrdom of St. Sacurninus). He confined himself principally to Auvergne, and is reckoned the first bishop of Auvergne, which see was afterwards transferred to Clermont. The Church of Auuvergne honors him as a martyr on Nov. 1. See Baillet, Nov. 1; Gregory of Tours, i, 23,29.
