# Themistoclea

Themistoclea (/ˌθɛmɪstəˈkliːə/; Greek: Θεμιστόκλεια Themistokleia; also Aristoclea (/ˌærɪstəˈkliːə/; Ἀριστοκλεία Aristokleia), Theoclea (/ˌθiːəˈkliːə/; Θεοκλεία Theokleia); fl. 6th century BCE) was, according to surviving sources, Pythagoras’ teacher while a priestess at Delphi. She is also considered one of the first European philosophers, though none of her works seem to have survived since the 6th century.

## Life

In the biography of Pythagoras in his Lives and Opinions of Eminent Philosophers, Diogenes Laërtius (3rd century CE) cites the statement of Aristoxenus (4th century BCE) that Themistoclea taught Pythagoras his moral doctrines:

   Aristoxenus says that Pythagoras got most of his moral doctrines from the Delphic priestess Themistoclea.

Porphyry (233–305 CE) calls her Aristoclea (Aristokleia), although there is little doubt that he is referring to the same person. Porphyry repeats the claim that she was the teacher of Pythagoras:

   He (Pythagoras) taught much else, which he claimed to have learned from Aristoclea at Delphi.

The 10th-century Suda encyclopedia calls her Theoclea (Theokleia) and states that she was the sister of Pythagoras, but this information probably arises from a corruption and misunderstanding of the passage in Diogenes Laertius.

   Themistoclea was a 6th century seer or Pythia of Apollo at the temple at Delphi. In Greek, themis refers to divine order or natural law. She is reputed to have been the teacher of Pythagoras, the great mathematician of Samos who believed that the workings of the material world could be expressed in terms of numbers.

Themistoclea represents an ancient epistemological approach which wedded experience, reason and the supernatural. As the Prophetess of Apollo at Delphi she would have been a source of much ancient wisdom, including knowledge of the natural world, astronomy, medicine, music, mathematics, animal husbandry and philosophy. She would have offered advice pertaining to sowing and harvests, whether to go to war, and who and when to marry.

   In Diogenes Laeterius’ work, The Lives and Opinions of Eminent Philosophers, in the section concerning the "Life Of Pythagoras," Diogenes states that "Aristoxenus asserts that Pythagoras derived the greater part of his ethical doctrines from Themistoclea, the priestess at Delphi.
