The Mouth of Sauron's part in The Lord of the Rings is quite small. In fact, Tolkien devotes little more than three pages to him. Yet with masterful strokes he paints the Mouth of Sauron in such a way as to make his character plain, telling us more about him in a few paragraphs than a lesser writer could in a whole chapter. For example, there is the passage wherein we learn of his hopes for the future, once Sauron the Great has triumphed and made himself Lord of all Middle-earth: "West of the Anduin as far as the Misty Mountains and the Gap of Rohan shall be tributary to Mordor, and men there shall bear no weapons, but shall have leave to govern their own affairs. But they shall help to rebuild Isengard which they have wantonly destroyed, and that shall be Sauron's, and there his lieutenant shall dwell: not Saruman, but one more worthy of trust." The lieutenant he alludes to is of course himself, as Tolkien makes clear in the next couple of lines, revealing Mouth's ambition and lust for power.
