Iaso (also, Iaso Tholus or Jaso; in Ionian Greek, Ieso) was the Greek goddess of recovery. The daughter of Asclepius, she had three sisters and one step sister: Panacea, Aceso, Aglæa/Ægle, and Hygeia. She helped the sick and diseased along with Panacea, Aglæa, and Hygeia. She is often identified with the Roman goddess Meditrina.
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'."
Pausanias (author of Periegesis of Greece) wrote of Amphiaraus in Oropos, Attica, in the 2nd century A.D. this:
Aristophanes mentions Iaso humorously in Ploutos, when one of the characters, Cario, reports that Iaso blushed upon his passing gas.
Although Iaso is from Greek iasthai, "to heal", it is likely that her name is related or was influenced by Isis, the Hellenized form of the Egyptian goddess Aset, who was, among other attributes, a goddess of healing. Obvious similarities can also be drawn from a comparison with the Hindu god Issa (who, incidentally, has been claimed to be Jesus. See The Unknown Life of Jesus by Nicholas Notovich, 1894), as well as with several of the names of Bacchus and Zeus.
