William Butler Yeats was an Irish poet and one of the foremost figures of 20th century literature. He studied poetry in his youth and from an early age was fascinated by both Irish legends and the occult. One of his works, 'The wind among the reeds', published in 1899, by critics' opinion is the main achievement of his early works. Imagery of Yeats' poetry at this time is filled with characters of Celtic mythology and folklore. (ShiNeko, Wikipedia)
