"gentlemen of the Aesculapian art "

Aesculapius was the Ancient Greek god of medicine and healing.  His daughters were Hygieia (Hygiene, goddess of health, cleanliness, and sanitation), Iaso (goddess of recuperation from illness), Aceso (goddess of the healing process), Aglaea (goddess of beauty, splendor, glory), and Panacea (the goddess of universal remedy). Aesculapius was the son of Apollo, and shared with Apollo the epithet Paean (the Healer). The rod of Asclepius, a snake-entwined staff, remains a symbol of medicine today.
