Martyrius the Sinaite

Saint Martyrius the Sinaite, also called Martyrius of Rukumija, is one of the Sinaite fathers of the Serbian Church. The Sinaites were hesychast monks from the circle of the disciples of Saint Gregory of Sinai, who settled in Serbia at the end of the fourteenth century and in the fifteenth; the list of Serbian saints counts together Romylus of Ravanica, Romanus, Nestor, Martyrius, Sisoes, Zosimas of Tuman, Job and Gregory of Gornjak.

The surviving sources give no details of Martyrius' own life. He is commemorated on 6 May in the old style, which is 19 May in the new, together with the other Sinaites; another day of the Sinaites in the Serbian list is 16 January, old style.
