In Greek as well as Roman mythology, was one of the Aeclepiadae; the sons and daughters of the god of medicine, Asclepius, and the goddess of healing, Epione. She was the goddess/personification of health, cleanliness and hygiene. Hygieia 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". Hygieia was imported by the Romans as the goddess Valetudo, the goddess of personal health, but in time she started to be increasingly identified with the ancient Italian goddess of social welfare, Salus.
