Physician and Burier of the Martyrs
Nicander's profession as a physician is the defining detail of his life as the synaxarion preserves it. His medical calling gave him both the means and the occasion to attend to suffering Christians, and the tradition presents his care for the imprisoned and his burial of the dead as a single continuous ministry of mercy carried out under threat of death.
The nocturnal burial of martyrs' remains was itself a perilous act during the Diocletianic persecution, when the public exposure of executed Christians was intended to deter the faithful and deny the dead the honor of a grave. By recovering and interring these bodies, Nicander defied that intent; his own martyrdom followed directly from this work.
