Does anyone know where the symbol of

Question

the snake came from ,that represents the medical corp.

Answer 1

This is what wikipedia says:

The caduceus (/kəˈduːsiəs/, -ʃəs, -ˈdjuː-; κηρύκειον in Greek) or wand of Hermes is typically depicted as a short herald's staff entwined by two serpents in the form of a double helix, and sometimes surmounted by wings. In later Antiquity the caduceus may have provided the basis for the astrological symbol representing the planet Mercury and in Roman iconography was often depicted being carried in the left hand of the Greek god Hermes, the messenger of the gods, guide of the dead and protector of merchants, gamblers, liars and thieves.

Ironically, the caduceus has come to be used as a symbol for medicine, especially in North America, through confusion with the traditional medical symbol, the rod of Asclepius, which has only a single snake and no wings.

AND THEN WIKI EXPLAINS:

The rod of Asclepius (also known as the rod of Asklepios, rod of Aesculapius or asklepian[1]) is an ancient Greek symbol associated with astrology and with healing the sick through medicine. It consists of a serpent entwined around a staff. Asclepius, the son of Apollo, was a practitioner of medicine in ancient Greek mythology.
