This document provides an overview of sonnets, including their origin and structure. It notes that sonnets are 14-line poems that typically have a strict rhyme scheme. It discusses how the Italian poet Petrarch is credited with perfecting the form in the 14th century. His sonnets were divided into an 8-line octet and 6-line sestet, with the octet presenting an idea and the sestet responding to it. It provides an example sonnet by Petrarch that was later translated by Wyatt to demonstrate the rhyme scheme and structure of a typical Petrarchan sonnet.
