Sources and Attestation
The principal notice of Jeremiah and Archilias is a brief synaxarion entry, which states only that they suffered in the third century and that they were mentioned by Saint Gregory the Dialogist. The priest's name also appears in the forms Archilius and Alchimius.
Liturgical calendars of the Eastern Orthodox Church list them on April 6 as 'Hieromartyr Archilias, Priest, and Martyr Jeremiah, of Rome,' which preserves the Roman association and the third-century dating. Beyond these short notices no detailed account of their lives survives.
