On [this] day St. Vindemialis, Bishop and Martyr, along with the bishop saints Eugenius and Longinus, who had striven against the Arians with their teaching and with miracles, were condemned by King Huneric to be tortured by various torments and then beheaded. – Roman Martyrology for May 2
The Roman Martyrology lists 16 martyrs named Eugenius. One of them was the St. Eugene most likely pictured at left, who according to the Martyrology was beheaded by the Arian king Huneric. No other "Saint Eugene" in the Martyrology is said to have been decapitated.
At right, Carlo Loth's Martyrdom of St. Eugene shows the saint both before and after the beheading. Behind him a soldier prepares to behead another of the bishops with the sword in his right hand. Presumably the cudgel in the hand of the man in the right edge of the painting represents one of the "various torments" in the account. Perhaps the man pointing to Heaven is Vindemialis.
