Hygeia in Wikipedia
            In Greek and Roman mythology, Hygieia (Greek Ὑγιεία or Hygeia 
Ὑγεία, Latin Hygēa or Hygīa), was a daughter of the god of 
medicine, Asclepius. She was the goddess of health, 
cleanliness and sanitation. She also played an important part 
in her father's cult. While her father was more directly 
associated with healing, she was associated with the 
prevention of sickness and the continuation of good health. 
Her name is the source of the word "hygiene"...
