Martyr Luxorius
† ок. 303-304
Luxorius of Sardinia — a Roman soldier-apparitor to Delphius, governor of Sardinia, converted to Christ through reading the Psalms and beheaded under Emperor Diocletian (c. 303-304) together with the newly baptized youths Camerinus and Cisellus; venerated in the West as patron of Cagliari, but with no confirmed Orthodox veneration.
Luxorius was a Roman soldier serving as apparitor (attendant) to Delphius, governor of the province of Sardinia. According to tradition, he was converted to Christ through reading the Psalter. He was baptized and openly confessed the faith, for which he was seized during the persecution of Emperor Diocletian.
He was beheaded at Forum Traiani (modern Fordongianus, near Cagliari) around 303-304, together with two youths recently baptized — Camerinus and Cisellus. His Passion ("The Martyrdom of Luxorius, Cisellus, and Camerinus") survives in a Latin text composed in Cagliari between the 6th and 10th centuries. A church dedicated to him, San Lussorio, stands near Fordongianus; he is venerated as patron of Cagliari.
The Western (Catholic) tradition keeps his feast on August 21 by the Gregorian calendar.
HONEST CAVEAT ON ORTHODOX VENERATION: thorough verification (pravenc.ru, azbyka.ru, drevo-info.ru, days.pravoslavie.ru, orthodoxwiki.org) found NOT A SINGLE source confirming veneration of Luxorius in Orthodox tradition — Russian or Greek. All substantive sources about him are exclusively Western (the Roman Martyrology, Catholic hagiography). Unlike a number of other pre-schism Western saints whose veneration by the Eastern Church is confirmed (e.g., St. Martin of Tours), no such confirmation was found for Luxorius. Given the absence of evidence of Orthodox veneration, the entry has been temporarily removed from the calendar (show_in_calendar=false) without inventing a date; the text has been kept as an honest historical note.
