Nicomediae sancti Hadriani Martyris, cum aliis viginti tribus, qui omnes, sub Diocletiano Imperatore, martyrium crurifragio consummarunt. Eorum reliquiae, a Christianis Byzantium delatae, reverenti honore sepultae fuerunt; inde postea sancti Hadriani corpus Romam translatum fuit sexto Idus Septembris, quo die festivitas ejus potissimum celebratur.
