Historical Record
The entirety of the preserved account is contained in a single sentence: that Eulampius lived in Palestine and was put to death by the sword for his faith. Calendar sources—the OCA Synaxarion, OrthodoxWiki, and the Holy Trinity Orthodox Church calendar—each carry this notice with no additional content.
No source supplies a birthplace, a death date, the name of the emperor under whom he suffered, fellow martyrs, or any account of relics or later glorification. His commemoration falls among more than thirty entries observed on March 5.
