What is the 13th constellation?

The 13th constellation on the zodiac belt Ophiuchus, honours the ancient medical healer known by the Ancient Greeks as ‘Aesclepius’ and Egyptians as Imhotep. Aesclepius, the son of Apollo and the mortal princess Coronis, was raised and mentored by the centaur Chiron, who instructed him in the art of medicine. In time, Aesclepius became famous as a miracle-working medicine man, and was later given a magical healing potion by the goddess Athena made from the blood of the snake-haired Gorgon. However, Aesclepius offended Zeus by using the potion to raise the dead for money, and therby upsetting the natural order of the universe.

What is the snake symbol in medicine?

Today, the symbol for the field of medicine is depicted by Aesclepius’ snake-entwined staff although a staff with two snakes known as a caduceus, is sometimes mistakenly used instead. The origin of the ancient serpent and rod symbol probably relates to the practice used at the time by physicians, for curing infection by “guinea worm,” or Dracunculus medinensis. The filarial worm would crawl around under the skin of the victim’s body, but could be removed by the physician by cutting a slit in its path, before carefully winding the worm around a stick until the pest had been removed. It is believed that a sign with the worm on a stick is how physicians advertised their services at the time.
