Sources and Tradition
The account of Marcian's life and death survives as a brief synaxarion notice rather than a detailed vita, and little is recorded of him beyond his youth, his preaching at Iconium, his trial before Perennias in Cappadocia, and his beheading. Western martyrological summaries identify the same figure (as Marcian of Lycaonia) but differ on details such as the year and the commemoration date; the Orthodox synaxarion's July 13 feast and the date of about 258 are followed here.
