Radagast
Radagast the Brown is one of the five Wizards, or Istari, sent to Middle-earth to contest the power of Sauron. Unlike Saruman the White, who delved into the arts of the Enemy, or Gandalf the Grey, who walked among Elves and Men, Radagast dwelt at Rhosgobel, near the borders of Mirkwood, and devoted himself to the lore of herbs, beasts, and birds. He was a master of shapes and changes of hue, and his friendship with the creatures of the wild was his chief strength. Yet his simplicity and trust made him a tool in Saruman's treachery, and his single errand to Gandalf had consequences that rippled through the entire War of the Ring.
Role in the War of the Ring
Radagast's sole direct intervention in the great events of the age occurred at the end of June, in the year 3018 of the Third Age. Gandalf, riding to the southern borders of the Shire with a foreboding of danger, encountered Radagast sitting on a bank beside the road near Bree. Radagast, a stranger in those parts, had been seeking Gandalf with an urgent errand. He whispered the news that the Nine Nazgûl had crossed the River secretly and were moving westward, disguised as riders in black. They were asking for news of a land called the Shire. This was the first confirmation Gandalf received that the Enemy's hunt for the Ring had begun in earnest.
Radagast delivered this message not on his own initiative but at the command of Saruman the White, who had told him to say that if Gandalf felt the need, he should seek aid at Isengard at once. Trusting Saruman as the head of his order, Gandalf took this as a hopeful sign and decided to go to Orthanc. Radagast, having fulfilled his task, was about to ride off immediately, but Gandalf stopped him and asked him to send messages to all the beasts and birds that were his friends, telling them to bring news to Saruman and Gandalf at Orthanc. Radagast agreed and departed. This request, made in good faith, proved to be the undoing of Saruman's plot, for Radagast, knowing no reason to do otherwise, rode towards Mirkwood and sent the Eagles of the Mountains far and wide. They saw the gathering of wolves, the mustering of Orcs, and the Nine Riders going to and fro, and they heard news of Gollum's escape. It was Gwaihir the Windlord, sent by these tidings, who later rescued Gandalf from the pinnacle of Orthanc.
Character and Limitations
Radagast is consistently portrayed as a figure of limited understanding in the affairs of the great. Saruman, in his scorn, called him "Radagast the Bird-tamer! Radagast the Simple! Radagast the Fool!" Gandalf himself, while acknowledging Radagast as a worthy Wizard, noted that he was "a master of shapes and changes of hue" and had "much lore of herbs and beasts, and birds are especially his friends." His mind was not subtle or political; he was easily deceived by Saruman's feigned friendship. When Gandalf met him, he caught no hint of wrong in Radagast's voice or eye, and concluded that Saruman had concealed his mind and deceived his own messenger. Radagast sought Gandalf in good faith and so persuaded him to walk into the trap of Isengard.
Significance and Legacy
Radagast's role, though brief, is crucial to the plot. His warning forced Gandalf to act, and his innocent compliance with Gandalf's request to send the Eagles ultimately led to Gandalf's rescue from Orthanc. Without Radagast, Gandalf might have remained a prisoner, and the Quest of the Ring would have failed before it began. Yet Radagast himself vanishes from the story after this point. He is not present at the Council of Elrond, nor does he take part in the final battles. His fate is left untold, but his simple, honest nature stands in stark contrast to the treachery of Saruman and the deep wisdom of Gandalf. He represents the power of the natural world, a force that, while not decisive in the war against Sauron, nonetheless played an indispensable part in the turning of the tide.
