Sources and Uncertainty
Hermogenes belongs to the sparsely documented company of early Sicilian and pre-schism Western saints whose memory survives chiefly through calendar notices rather than full lives. English-language references are limited to short entries in the synaxaria and liturgical lists for November 24, which agree on his title and see but differ on his dating.
Because the record is so thin, scholarly and liturgical sources hedge on when he lived. One tradition places him in the early ninth century, the period to which his peaceful repose is usually assigned; other listings note an alternative dating centuries earlier. No detailed account reconciles the two, and the saint is best identified simply as a bishop of Agrigentum commemorated among the hierarchs.
