Lamia archetype in Coleridge and Keats

In Keats' "Lamia" references to ancient Greek mythology/theology is used frequently such as with " She was a gordian shape of dazzling hue"(50) which compares Lamia to the gordian knot which is snakelike in various ways. On the one hand, the gordian knot is a trick and feeds the Lamia archetype as deceptive and seductive; also, the physical shape of the gordian is snakelike. A similar approach is used in Coleridge's "Christabel" which also describes Cristabel as the snake both physically and metaphorically. In Keats' "Lamia", Lamia is trying to avoid Lycius by transforming into the snake whcih seems to vindicate that Lamia is not a sinister character and that Lycius is at fault and is responsible for entering into a world of sin. It presents sort of a paradox, the capacity Lamia possesses over man and thus the Lamia archetype is materialized in the man's own lust and inability to forbear impulses. Overall, it appears that Keats is more sympathetic to the Lamia.
