Lady of Shalott Explication

Explication of “The Lady of Shalott”
The “Lady of Shalott” by Lord Alfred Tennyson is a rich poem about the isolated role of the artist.   It is written in four parts.   Each part serves a certain role in the poem and assists in moving the plot along.   It is written in iambic and trochaic tetrameter which lends the poem a songlike, simple rhythm. The rhyme scheme is aaaabcccb.   Both the rhythm and the rhyme contribute to the whimsical quality of the poem that makes it seem like a fairy tale upon first reading.

The gray walls imposing themselves on the Lady of Shalott indicate that she is trapped and very removed from the world.   Her prison looks over some flowers, but the Lady of Shalott is unable to interact with her surroundings.   This imagery paints a vivid picture of the Lady’s isolation.
