Mark of Durostorum

Saint Mark of Durostorum was a martyr of the city of Durostorum (present-⁠day Silistra), commemorated by the Bulgarian Orthodox Church. Very little is known of him: he is honoured on 8 June together with the martyr Julius, which suggests that he suffered at the same time as Julius, probably in the persecution of Diocletian.

Julius was born at Durostorum into a pagan family and had served twenty-⁠seven years in the Roman army, among others in the Eleventh Claudian Legion; as a veteran he became a Christian. Brought before the governor Maximus, he refused to sacrifice to the Roman gods and in the year 304 was condemned to be beheaded. For Mark the source says nothing further.
