Luis de Góngora is a 17th century baroque poet. He does not write poetry for the masses he only writes for the educated hierarchy. He ensures this by employing techniques such as culteranismo and conceptismo which are both evident in "Soneto CLXVI". The main themes evident in "Soneto CLXVI" are time and beauty and how beauty doesn 't last through time. Góngora often writes poetry which focuses on the "tempus fugit" or the "carpe diem" element of life and this poem is no different. Sor Juana Inés de la Cruz is one of the last great baroque poets. She was a nun, but not by vocation. This poem is also about how beauty decays over time however in contrast to Góngora 's poem, which is about an unnamed woman, De La Cruz 's Sonet 145 is about herself. Also there is the further theme of beauty as a lie, or a trick, to deceive us into thinking that we are doing somthing more other than passing through time, waiting to die.
Góngora 's "Sonet CLXVI" has 14 hendecasyllabic lines. It has two quatrains and two tercets. The rhyming scheme is ABBA, ABBA, CDC, DCD. "Sonet 145" has the exactly same form. This form is extremely common is baroque poetry. The first quatrain in both poems function as a complete clause. The poems both immediately address a person, a “you,” However this "you" serves a different purpose is both poems. In Sonet CLXVI the "you" is the beautiful girl who he is urging to enjoy her beauty but in Sonet 145 the is it "you" who is looking at the painting, which is the
