While it is well known that some American writers, such as Ralph Waldo Emerson, Henry David Thoreau, Walt Whitman, and so on had great enthusiasm for the East, Emily Dickinson has been an exceptional American poet who does not deal with any topic on the East. She seemed to have a reclusive life and have no interest in the East, however, recent studies by Cristanne Miller, Yanbin Kang, and other Dickinson scholars have revealed that she had also a keen interest in the East, and wrote some poems on it. On the basis of these recent studies on Dickinson and the East, this paper is going to investigate the ways in which she encountered and invented the East in her poetic works, and articulate its meaning and significance. Her visit to the Chinese Museum at the Malboro’ Chapel of Boston at her age of sixteen, her life-long gardening of the Asian flowers at her homestead, her intensive readings on the East in Emerson’s Poems, Thomas Wentworth Higginson’s publications in The Atlantic Monthly and the various news on the East in The Springfield Republican helped her shape her own idea on it. She usually visualized the East as a spectacular sunrise, but transformed its stereotypical idea of her contemporaries into a revolutionary one. Her imaginative idea on the East challenges not only the puritanical ideas on death but also the imperialistic idea on the East. As her use of the punctuation marks, lineation, and fascicles makes her poems distinctive, her concept on the East gives her work a rich and significant dimension.
