Account of the Martyrdom
The Orthodox synaxarion relates that Bianor was a native of the Pisidia district of Asia Minor and was brought before the prefect of the city of Isauria in Lykaonia, who demanded that he renounce Christ. Bianor stood steadfast in the faith despite the tortures inflicted upon him.
Silvanus is presented not as a fellow prisoner but as a bystander whose conversion was occasioned by the spectacle of Bianor's constancy. Having witnessed the martyr's endurance, he confessed Christ openly; his tongue was cut out and he was then beheaded. Bianor was beheaded after a longer ordeal of torture.
A Greek synaxarion tradition records a more detailed catalogue of Bianor's sufferings before a governor it names Severian — including suspension, beating, burning, the extraction of his teeth, the cutting off of his ears, the piercing of his ankles, the removal of an eye, and scalping before his beheading. These specifics are particular to that source; this same tradition also notes uncertainty in the manuscript place-name, suggesting it may refer to Aphrodisias rather than the locale as transmitted.
