Radagast the Brown

Radagast is another of the wizards of Middle Eart, one of the Maiar from Valinor. His original name was Aiwendil, meaning bird-friend in Quenya. According to the essay “The Istari” from the Unfinished Tales, the name Radagast means “tender of beasts” in Adûnaic, the language of Númenor. He played a part in the White Council, which was formed to stand against Sauron, but it seemed his greatest concern was with the Kelvar and Olvar (flora and fauna) of Middle-earth and little else is told of him in the chronicles of that time. He was wiser than any Man in all things concerning herbs and beasts. It is said he spoke the many tongues of birds. Even the Beornings and Woodmen of Mirkwood and the Mighty Ent guardians of the Forest of Fangorn spoke with reverence of the wisdom of Radagast the Brown, for in forest-lore he had no equal.
