Saint Macrobius was from Paphlagonia, and suffered martyrdom with Saints Gordian, Elias, Zoticus, Lucian and Valerian.
Gordian and Macrobian served in the imperial court, and they enjoyed the particular favor of the emperor. When he found out that they were Christians, he sent them to Scythia. There they met Zoticus, Lucian and Elias, who were also courageous confessors of Christ. First Saints Gordian and Macrobius suffered. After this Saints Elias, Zoticus, Lucian and Valerian were tortured and then beheaded in the city of Tomis in Scythia (Tomis, Romania). They suffered at Paphlagonia (Asia Minor) at the beginning of the fourth century during the reign of the Roman emperor Licinius (311-324).
