Sonnet 51 is one of 154 sonnets written by the English playwright and poet William Shakespeare. It is part of the Fair Youth sequence, in which the poet expresses his love towards a young man. It is a continuation of the argument from Sonnet 50. According to the Norton Anthology, sonnet 51 is considered part of the "long sequence" (18-126) and focuses on the young man who Shakespeare wrote about in the preceding group of sonnets namely the first 17 sonnets known as the procreation sonnets. This poem focuses on a young man fighting time to return to his lover, and includes description of haste and timeliness. Source: Wikipedia (en)
