The Martyrdom of Saints Cosmas and Damian, by Fra Angelico.
September 27 is the traditional* feast date of early Christian saints Cosmas and Damian.
This has made them patron saints to doctors, surgeons, pharmacists, and dentists but decidedly not to insurers.
They were once much more widely known and revered than today, back when the mysteries of medicine and of faith intertwined with one another. The two are named in the Canon of the Mass, and multiple churches in Europe dubiously claim the honor the ancient doctors’ relics; their skulls alone reside simultaneously in Bremen, Vienna, and Madrid, while a church in Venice allegedly holds their non-cranial remains. Visitors to the Roman Forum will behold the beautifully preserved pagan Temple of Romulus, which was rededicated in 527 as the basilica of Santi Cosma de Damiano and still hosts weddings beneath its impressive Cosmas and Damian mosaic.
The saints’ day is observed in Brazil, where children on September 27 receive candies (Cosmas and Damian also count confectioners and children among their devotees). St. Anthony’s Church in Utica, New York, also hosts an annual Cosmas and Damian pilgrimage attracting thousands of people from across North America.
As two men intimate with one another who traveled and ministered together, they are sometimes speculatively ventured as early gay exemplars. (They’re traditionally accounted as brothers.)
