Saint Gallicanus
Roman martyr in Egypt in 363 AD

Saint Gallicanus was a Roman martyr in Egypt in 363 AD, during the reign of Julian. A former general, he converted to Christianity and retired to Ostia where he was involved in a variety of charitable works. The Emperor exiled him to Egypt, where he was later martyred.
Life
Gallicanus was from a prominent Roman family with important political connections.
According to his "Acta" (in Acta SS., June, VII, 31), he was a distinguished general in the war against the Persians. He was honored with a triumph and was held in affection by the emperor Constantine. He was also consul with Symmachus in 330 and perhaps also once before with Caesonius Bassus in 317.
According to a medieval legend, Gallienus was at one time the fiancé of Constantine's eldest daughter, Constantia and was converted to Christianity by her soldier bodyguards John and Paul. He then retired to Ostia, endowed a church built by Constantine I, and founded a hospital where he worked with Saint Hilarinus. There he washed the feet of the poor, prepared their table and served them, carefully waited on the infirm, and performed other works of mercy.

Why this record matters
“Saint Gallicanus” is worth following because a concise public description often conceals a longer documentary argument. Here, Saint, Gallicanus and Roman provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 16, 2026. The linked authority identifier is Q16965184. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
