Martyrdom
The brothers are said to have died separately as they were taken into exile, and their tradition preserves a distinct place and day for each. Eros (Erotas) died first, on June 22, at Parembol. Orentius, the principal martyr, was drowned, cast into the sea with a stone tied around his neck; his commemoration is kept on June 24, and one account places his death near Riza (Rize). Pharnacius died on July 3 at Kordila. Firmus and Firminus received their crowns together on July 7 at Aspara (Apsaros), on the eastern shores of the Black Sea. Cyriacus died on July 14 at Ziganeia (Zigania). Longinus, the last to die, reposed on July 28 while aboard a ship; the vessel ran aground at Pitinda (Pitsunda), where he was buried.
Although each brother has his own place and date of death, they are venerated collectively, with a shared feast on June 24.
