Saint Philetus (d. 121 AD), is along with Saints Lydia, Macedo(n), Theoprepius (Theoprepides), Amphilochius and Cronidas (Cronides), venerated as a Christian martyr. According to the Roman Martyrology, they were martyred in Illyria during the reign of Hadrian. The Martyrology also states that Philetus was a senator, that Lydia was his wife, Macedo and Theoprepius their sons, Amphilochius a captain, and Cronidas a notary. Their Acta are considered unreliable.
