Hygieia

Hygieia is a goddess from Greek mythology (more commonly spelled Hygeia, sometimes Hygiea; /haɪˈdʒiːə/; Ancient Greek: Ὑγιεία or Ὑγεία, Latin: Hygēa or Hygīa). Hygieia is a goddess of health (Greek: ὑγίεια – hugieia), cleanliness and hygiene. Her name is the source for the word "hygiene". Hygieia developed from a light personification to a full goddess within the cult of Asklepios. Together with her father, she appeared in dreams of patients who visited their temples. Patients performed the healing ritual temple sleep to get healed.

Hygieia is related to the Greek god of medicine, Asclepius, who is the son of the Olympian god Apollo. Hygieia is most commonly referred to as a daughter of Asclepius and his wife Epione. Hygieia and her four sisters each performed a facet of Apollo's art: Hygieia (health, cleanliness, and sanitation); Panacea (universal remedy); Iaso (recuperation from illness); Aceso (the healing process); and Aegle (radiant good health).
