Their story
St. Ambrose relates that Agricola was a gentleman of Bologna and that his slave Vitalis learned the faith from him and was martyred first. Vitalis praised God as long as he could speak, then prayed Christ to receive his soul.
Agricola was then nailed to a cross. In 393 St. Ambrose found their relics in the Jewish burial ground at Bologna, together with the nails and cross of Agricola's martyrdom. Butler places their arrest probably in 304; Baring-Gould gives the fourth century.
