Little bit about Darmesteter the translator/researcher
In 1875, he published a thesis on the mythology of the Avesta, in which he advocated that the Persian religion of Zoroastrianism had been influenced by Judaism (and not backwards as many scholars say).[1]
In 1877 became teacher of Persian language at the École des Hautes Études.
He continued his research with his Études iraniennes (1883), and ten years later published a complete translation of the Avesta and associated Zend (lit. "commentary"), with historical and philological commentary of his own (Zend Avesta, 3 vols., 1892–1893) in the Annales du Musée Guimet.
He also edited the Avesta for Max Müller's Sacred Books of the East series (vols. 4 and 23).[2]
Darmesteter regarded the extant texts as far more recent than commonly believed, placing the earliest in the 1st century BC and the bulk in the 3rd century AD.
