Hieromartyr '''Basil of Ancyra''', was a [[bishop]] in Ancyra, Galatia, (now Ankara, Turkey) during the fourth century. Originally, a member of the 'moderate' [[Semi-Arianism|Semi-Arian]] party he took a leading part in the [[Council of Seleucia]], but recanted the Semi-Arian formula and defended his orthodoxy against the threats of Emperor [[Julian the Apostate]], and died a [[martyr]]. He is commemorated on [[March 22]](and [[January 1]], see ''Notes on sources'').

The various sources (external links) about a Basil of Ancyra point to Basil being any of three persons: one being a former Semi-Arian bishop who recanted to become a martyred Orthodox (as presented in this article), the second a laymenlayman, perhaps a physician, who was martyred defending his faith under the persecutions of Julius the Apostate (as noted in the OCA article and remembered on [[January 1]])<ref>http://ocafs.oca.org/FeastSaintsLife.asp?FSID=100004</ref>, and the third, a priest of Ancyra, distinct from the bishop or the layman (celebrated on [[March 22 as ]] in the OCA article).<ref>http://ocafs.oca.org/FeastSaintsViewer.asp?SID=4&ID=1&FSID=100861</ref>
