The revered Holy Unmercenaries, also known as Anargyri, were physicians renowned for their selfless dedication to healing without seeking any reward. Even after their earthly repose, they continue to intercede and heal through their prayers for those who call upon them in faith. Among them are:
- Saints Cosmas and Damian (commemorated on October 17 and November 1)
- Saints Cyrus and John (honored on January 31 and June 28)
- Thallelaius (remembered on May 20)
- Samson (celebrated on June 27)
- Saints Cosmas and Damian (also commemorated on July 1)
- Hermolaüs (venerated on July 26)
- Panteleimon (acknowledged on July 27)
- Diomedes (remembered on August 16)
Though some question the existence of three distinct pairs of Anargyri named Cosmas and Damian, historical evidence suggests a single pair initially. However, the widespread veneration and dispersion of relics across the Empire led to the recognition of multiple pairs. Despite this, the Church’s Synaxaria have long commemorated all three pairs of Saints Cosmas and Damian as distinct entities, honoring their legacy of selfless service and healing.
