Agathius was a Greek centurion from Cappadocia who served in the imperial army during the early 4th century. Following his arrest in Perinthus for his Christian beliefs, he was subjected to torture by the tribune Firmus. He was eventually taken to Byzantium, where he was scourged and executed by beheading. Because he refused to renounce his faith, he was recognized as a martyr, with his death occurring around the year 303.
Veneration and legacy
His remains were moved to a spring near the Vivarium monastery in Italy around 630. This led to his recognition as San Agario in Squillace, where a relic of his arm later established him as a patron. In Spain, he is known as San Acato. He is also included among the Fourteen Holy Helpers in the Catholic tradition.
Cultural significance
In Slovenia, several churches are dedicated to him, and he was historically viewed as a patron for those fighting against Ottoman rule. This connection also made him a symbol of resistance for the Maniots in Greece. His feast day is traditionally observed on May 8.
