Iaso (also, Iaso Tholus or Jaso; in Ionian Greek, Ieso) was the
Greek goddess of recuperation from illness. The daughter of
Asclepius, she had five sisters:
Aceso,
Aglæa/Ægle,
Hygieia,
Meditrina, and
Panacea. All six were associated with some aspect of health or healing. Very little is actually known about Iaso. She was probably considered a
demigod, unlike her sister Panacea, who was given full "god" status. She did, however, have followers, the Iasides ("sons of Iaso"). In
Helena Petrovna Blavatsky's The Esoteric Character of the Gospels, the author says, "Iaso, the daughter of Asclepios, was the goddess of healing, under whose patronage were all the candidates for initiation in her father's temple, the novices or chrestoi, called 'the sons of Iaso'."
