Henry David Thoreau was also one of the writers of Transcendentalism, and his famous essay was Walden, in which he revealed the hidden spiritual possibilities in everyone’s life, and to considerate the pursuit of material things.

(3) High Romantics

Due to the great effort made by those geniuses such as Emerson and Thoreau, a wild-ranged national American literature had been laid a solid foundation by the mid-19th century.

There are four important names in American literature to remember from this period: Washington Irving (1783-1859), Walt Whitman (1819-1892), James Fennimore Cooper (1789-1851), and Edgar Allan Poe (1809-49).

Irving will long be remembered for his book of essays and stories, The Sketch Book of Geoffrey Crayon (1819), which helping this new nation started its first step confidently. Cooper and Whitman described the character of the nation, which combined the courage and cleverness of expansion, the great sense of destination, and the optimistic spirit together. Hawthorne and Melville expressed the dark side of American dream though their profound and symbolized works.

Walt Whitman (1819-1892), father of free verse, “he threw aside the traditional ornaments and prettiness of verse, and created his own form” (Wu Dingbo, 44). His Leaves of Grass (1855), which contains such well-known poems as I Hear America Singing, and Song of Myself, was regarded America’s first genuine epic poem. He rejected regular meter and rhyme in favor of flowing free verse and celebrated patriotic love, ragged individualism, democracy and equality and stressed an almost mystical identification with America.

Nathaniel Hawthorne (1804-1864), due to his family background, his works always concerned with sin, morality, romance, and had complex Puritanism. His masterpiece was the novel The Scarlet Letter, and his The House of Seven Gables was also well liked. In these works he presented material on the alienation between facts and fancy, by using many symbols and setting to reveal the psychology of the character.

Herman Melville was Hawthorne’s good friend, also an important novelist. Melville's greatest work, Moby Dick (1851) was based on Melville's adventures on the whaling ships. It is the deep "tragedies of human thought" that show his critical understanding of human nature. Today Melville is considered one of America's greatest writers today.

Romanism was extremely influenced in a rising America as America had always had a strong spiritual tradition and romanticism was very comfortable with American spiritual heritage and its ideals of democracy and equality. During this period, the American literature was so changeable that has never been before. Nathaniel Hawthorne, Herman Melville, Walt Whitman and Edgar Allan Poe, these four great writers had given depth and strength to American literature at that time.

4. Local Color And Realism: A New Flavor to American Literature

After the Civil War, the American society was in a turbulent situation through several economical crises. The writings about critical realism and unveiling the dark side of the society were increased. They were mainly focus on bankrupt in countries, difficult life or struggle of low-position people and so on. Thus Romanism was on the wane with passing days, while Realism rose and became more and more popular.
