Abstract: W.C.Williams lived in the period in which the visual arts developed fast. With explicit textual analysis, this paper attempts to probe into the relations between the writing idea and aesthetic techniques used in the poems and modern visual arts. Williams changed the traditional theme and form of poems and put forward a famous idea——"A poem can be made of anything" and created tensions in his poems. At the same time, he expanded the aesthetic dimension of poems by adoption of colors. As a result of these achievements, Williams became a milestone in the history of American poetry.
