Saint Philetus (Φιλητός) (d. 121) is, along with Saints Lydia (Λυδία), Macedo(n) (Μακεδών), Theoprepius (Theoprepides) (Θεοπρέπιος), Amphilochius (Ἀμφιλόχιος) and Cronidas (Cronides) (Κρονίδης), venerated as a Christian martyr. Philetus was supposedly "...a senator who resided in the province of Illyria and was put to death during the persecution under Emperor Hadrian]..."
According to the Roman Martyrology and Orthodox Synaxarium, 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.
