Wizard is a translation of Quenya istar (Sindarin ithron): one of the members of an ‘order’ (as they called it), claiming to possess, and exhibiting, eminent knowledg1e of the history and nature of the World. The translation (though suitable in its relation to ‘wise’ and other ancient words of knowing, similar to that of istar in Quenya) is not perhaps happy, since the Heren Istarion or ‘Order of Wizards’ was quite distinct from the ‘wizards’ and ‘magicians’ of later legend; they belonged solely to the Third Age and then departed, and none save maybe Elrond, Círdan, and Galadriel discovered of what kind they were or whence they came.

Men, therefore, grew to fear them, even when they loved them, and they were held to be of the Elven-race (with whom, indeed, they often consorted).
