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"...
Hygieia in Greek and Roman Biography and Mythology
（*(Ugi/eia), also called Hygea or Hygia, the goddess of
health, and a daughter of Asclepius. (Paus. 1.23.5, 31.5.)
In one of the Orphic hymns (66. 7) she is called the wife of
Asclepius; and Proclus (ad Plat. Tim.) makes her a daughter
of Eros and Peitho. She was usually worshipped in the same
temples with her father, as at Argos, where the two
divinities had a celebrated sanctuary (Paus. 2.23.4,
3.22.9), at Athens (1.23.5, 31.5), at Corinth (2.4.6), at
Gortys (8.28.1), at Sicyon (2.11.6), at Oropus (1.34.2). At
Rome there was a statue of her in the temple of Concordia
(Plin. Nat. 34.19). In works of art, of which a considerable
number has come down to our time, she was represented as a
virgin dressed in a long robe, with the expression of
mildness and kindness, and either alone or grouped with her
father and sisters, and either sitting or standing, and
leaning on her father. Her ordinary attribute is a serpent,
which she is feeding from a cup. Although she is originally
the goddess of physical health, she is sometimes conceived
as the giver or protectress of mental health, that is, she
appears as mens sana, or ὑλίεα φρενῶν (Aeschyl. Eum. 522),
and was thus identified with Athena, surnamed Hygieia.
