Shakespeare's sonnets
Shakespeare's sonnets are poems that William Shakespeare wrote on a variety of themes. When discussing or referring to Shakespeare’s sonnets, it is almost always a reference to the 154 sonnets that were first published all together in a quarto in 1609; however there are six additional sonnets that Shakespeare wrote and included in the plays "Romeo and Juliet", "Henry V" and "Love's Labour's Lost".
Petrarch's and Shakespeare's sonnets
Although Petrarch is accredited with perfection of the sonnet, Shakespeare still made changes in sonnet form and composition 200 years after Petrarch's death. While Petrarch's sonnets focused mainly on one hub, Shakespeare developed many subjects within his themes such as insomnia, slave of love, blame, dishonesty, and sickness. Despite creating complicated plots, Shakespeare also manages to place ulterior motifs among his two lovers, building new poetic form where Petrarch left off.
