Note 31 — Fabre d’Olivet

The Greek word Θρᾴκη, Thrace, in passing into the Ionian dialect Θρῄξ, has furnished the following expressions: θρῆσκος, a devotee, θρησκεία, devotion, θρησκηύω, I adore with devotion. These words, diverted from their real sense and used ironically after the cult of Thrace had yielded to that of Delphi, were applied to ideas of superstition and even of fanaticism. The point of considering the Thracians as schismatics was even reached, and the word ἐθελοθρησκεία composed to express a heresy, a cult particular to those who practised it, and separated from orthodoxy.
