The Roman god of medicine and healing, equivalent to Greek Asclepius, was Aesculapius.
Aesculapius was the Roman form of the Greek Asclepius, whose healing cult spread widely through the ancient Mediterranean. Roman tradition associated him with medical skill, recovery, physicians, and rejuvenation. His most recognizable symbol was a staff entwined by a single serpent, the Rod of Asclepius, which remains an emblem of medicine.
Myths describe Asclepius as the son of Apollo and Coronis, though ancient sources gave more than one version of his birth. The centaur Chiron taught him medicine, and his abilities became so great that stories credited him with restoring the dead. Zeus ultimately struck him with lightning for upsetting the boundary between life and death, after which he was honored as a god.
A common mix-up is the caduceus, a staff with two snakes, which belongs to Hermes or Mercury and is not the original medical emblem. “Asclepius” is the Greek name; “Aesculapius” is its Latinized Roman counterpart.
