Medusa

In Greek mythology, Medusa was a monster, a Gorgon, generally described as a winged human female with living venomous snakes in place of hair. Those who gazed upon her face would turn to stone. Most sources describe her as the daughter of Phorcys and Ceto, though the author Hyginus makes her the daughter of Gorgon and Ceto. According to Hesiod and Aeschylus, she lived and died on an island named Sarpedon, somewhere near Cisthene. The 2nd-century BCE novelist Dionysios Skytobrachion puts her somewhere in Libya, where Herodotus had said the Berbers originated her myth, as part of their religion.

The first line comprises a triplet of three related words. This could be described as a semantic field. It is also a device known as a tricolon, that is, three related words or phrases that give balance and completeness. Here, ‘suspicion’, ‘doubt’ and ‘jealousy suggest evolving insecurity as the emotions implied in the words become stronger. Medusa increasingly lacks confidence, is insecure and worried her husband will betray her

Rhetorical Questions- constant question of identity because jealousy has taken her over and she doesn't recongize herself when she looks in the mirror (loss of identity)

The word ‘yellow’ has connotations of disease and decay while the repetition of the word ‘foul’ serves to highlight the disgust of her transformation. The words ‘mouthed’ and ‘tongued’ and ‘fanged’ are half rhymed and obviously related. 

Lines three and four comprise two rhythmically matching triplets.
- The first triplet describes a beautiful Greek-god
- The second triplet describes his betrayal.
The lines end with the rhymed ‘own’ and ‘home’. This neatly encapsulates the root cause of the damage he has done to Medusa, and the result — her wish for him to become the rhyming ‘stone’.
