 The exact date of its composition is unknown, it is thought that the Fair Youth sequence was written in the first half of the 1590s and was published with the rest of the sonnets in the 1609 Quarto.While "sonnet" originally referred to any short lyric, the "English" (or "Surreyan" or "Shakespearean") sonnet has a definite form.The English sonnet contains three quatrains followed by a rhyming couplet.
