Saint Gorgonius of Nicomedia was a Christian martyr, part of the group Gorgonius, Peter Cubicularius and Dorotheus, who died in 304 AD at Nicomedia during the persecution of Emperor Diocletian.
According to Lactantius and Eusebius, Gorgonius held a high position in the household of the emperor. When the persecution began he was consequently among the first to be charged, and with his companions, Peter, Dorotheus and several others, brutally tortured to death.
According to one version of the legend, Diocletian, wishing to expose Christians in his household, ordered everyone to pay honor to the Roman gods; if they refused, they would be exposed as Christians. The first to be exposed was Diocletian's butler, Peter, surnamed Cubicularius, who was strung up, his flesh torn from his bones. Two Christians, Dorotheus, an imperial chamberlain, and Gorgonius, an army officer, protested this treatment, and were also martyred, together with another official, named Migdonius. In the meantime, Peter was boiled or burned alive, or “roasted on a gridiron.”
