Asclepius (also spelled "Aesculapius") was the Greek god of medicine and healing.
A variation on his symbol was present on Aquan objects on Argo. (TAS: "The Ambergris Element")
His name was used in a version of the Hippocratic Oath spoken by The Doctor in 2373. (VOY: "Darkling")
The quote from the USS Pasteur's dedication plaque used an alternate "Aesculapius" spelling of his name in the first part of the Hippocratic Oath. (TNG: "All Good Things...")
