Epic+Simile12

" Her legs - and there are twelve - are like great tentacles, unjointed, and upon her serpent necks are borne six heads like nightmares of ferocity, with triple serried rows of fangs and deep gullets of black death." (pg. 212)

This simile is comparing Sklla's legs to great tentacles. It also says her six heads are like nightmares of ferocity. This means that they are horribly frightening, like a nightmare. These comparisons really help the reader understand just how scary Sklla is.
