According to the Roman Martyrology and texts in the Acta Sanctorum, Caprasius hid in a cave during the persecution of Diocletian until he learned of the martyrdom of St. Foy and her steadfastness under torture. He prayed that he too might be judged worthy of martyrdom, and suddenly a stream of water sprang from the wall of the cave.
This miracle gave Caprasius assurance that the Lord did indeed find him worthy of the crown of martyrdom, so he went to the city square and declared publicly for Christ. Spurning Dacian's offer of gifts if he were to recant, he was put to death. His example led others to confess their faith as well, including two brothers named Primus and Felicianus.
According to legend, the stream from the cave continued to flow perpetually in Agen.
One text says Caprasius was beheaded, another that his
flesh was torn to pieces. The 19th-century painting at
right shows him with a collection of instruments that seem
to cover both possibilities – for beheading, a sword; for
hacking, an axe and adze. Also on the ground is a martyr's
palm. Although he is not listed as a bishop in the Roman
Martyrology, he is shown here with a mitre and crozier
because local tradition holds that he was the first bishop
The painting, by Jean-Baptiste Delmas, is in the Musée Fau in Conques. One would think that the city in the background should be Agen with its 12th-century cathedral, but the pointed spire in the picture is quite different from the square tower of the actual church (image) or the double towers in Conques (image).
