Alexander of Bergamo was a Roman soldier, possibly a centurion of the Theban Legion, who lived during the early 4th century. Born in Rome, he was martyred in Bergamo around 303 for refusing to abandon his Christian faith. After surviving decimation at Agaunum, he was held in Milan's Zebedeo Prison, where he eventually escaped with the assistance of Fidelis. His resistance to Roman religious practices, including the destruction of a sacrificial altar in Milan, eventually led to his execution by decapitation.
