Catholic Encyclopedia: Saints Basilides

Saints named Basilides are mentioned in old martyrologies on 10, 12, and 28 June. The first date belongs to a Roman martyred on the Via Aurelia. The entry for June 12 appears to mix up several stories, and this Basilides is most likely the same as the martyr of June 10. The third St. Basilides was a soldier or court official martyred in Alexandria, who is mentioned in Eusebius's Ecclesiastical History.
