Great martyr

Great Martyr or Great-Martyr (Greek: μεγαλομάρτυρ, megalomartyr, from megas, "great" + "martyr") is a classification of saints who are venerated in the Eastern Orthodox Church and those Eastern Catholic Churches which follow the Rite of Constantinople.

Generally speaking, a Great Martyr is a martyr who has undergone excruciating tortures—often performing miracles and converting unbelievers to Christianity in the process—and who has attained widespread veneration throughout the Church. These saints are often from the first centuries of the Church, before the Edict of Milan. This term is normally not applied to saints who could be better described as hieromartyrs (martyred clergy) or protomartyrs (the first martyr in a given region).
