In Aegypto sanctorum Martyrum Marci et Marciani fratrum, et aliorum ferme innumerabilium utriusque sexus atque omnis aetatis; quorum alii post verbera, alii post diversi generis horribiles cruciatus flammis traditi, alii in mare praecipitati, nonnulli capite caesi, plurimi inedia consumpti, alii patibulis affixi, quidam etiam, capite deorsum verso et pedibus in sublime sublatis, appensi, beatissimam martyrii coronam meruerunt.
