William Shakespeare writes the sonnet that I am going to analyze. It is divided into three quatrains and in a rhyming couplet. This is the 20th sonnet of a collection of 154 poems; the reader can understand this because the title comes from the first line. The speaking voice used a metaphor to underline the beauty of the protagonist like a woman, because Nature has painted her/his face. He also means that his love connects male and female beauty in a single beauty (“the Master Mistress of my passion”). Talking about the Fair Youth's eyes he says that his eyes are more shining that the eyes of women.  The speaking voice underlines how at first Nature wanted to create him as a woman but seems his creation was so beautiful and Nature is a woman too, so she fell in love with her beauty and therefore added something that was without value for a man but guaranteed a woman's pleasure. Therefore, women love this man for their pleasure, but Shakespeare love him only for love.                                                                                                               The sonnet ends with an invocation the poet makes: he wants to enjoy the fair youth love and leaves his love to women.The speaking voice is addressed to a man who is so handsome that he amazes both women and men. Beauty is not the only quality of this person, he has got a woman's gentle heart but not acquainted with shifting change, and his eyes are brighter than women’s eyes.In this sonnet, we find the themes of love, beauty and passion. Real beauty should assemble both men and women characteristics.
