Asclepius

Asclepius was an Olympian. He lived in the temple of Olympus, where he served as a scientist and doctor. The life spores were stored in Asclepius's laboratory, where he used them to create men as experimental specimens, hoping to perfect them according to Zeus's wishes. He carried a mechanical rod which could non-intrusively scan a specimen's biology; when the Fourth Doctor was sent his lab, Ascelpius scanned him and was intrigued to find that he had two hearts.

Marc described the Welkin Sanatorium and Centre for Wellness as a temple of Asclepius. (AUDIO: The Lost Resort)

Appearance
Ascelpius was taller and larger than a human. When he met the Fourth Doctor, he looked like a balding elderly man, with long white hair and a beard. (COMIC: The Life Bringer!)
