SS. Acius and Acheolus, Martyrs of Amiens
[Called in French SS. Ach and Acheul.] THEY seem to have suffered about the year 290, and are honoured in the Gallican Martyrologies, and especially at Amiens, on the 1st of May. See Molanus in Auctario Usuardi, and Henschenius 1st of May, and an old Martyrology under the name of St. Jerom, quoted by him.
The church of St. Acheul, without the walls of Amiens, was originally the cathedral; but this being removed by St. Salvius to our Ladys in the city, the church of St. Acheul became dependent on it. A community of regular canons was there erected in 1145. It is now a member of the reformed congregation of St. Genevieve. In digging foundations for a new church, five very ancient tombs were found, which have been the subject of many dissertations, especially whether one is not that of St. Firminus, bishop and confessor, whose relics are enshrined in the cathedral.
