The Innocent and The Temptress

Cristabel is initially described as a helpless, innocent, girl who needs a man's protection and guidance.  There is no such pretence in Lamia.  She is automatically described as the seductress that even Nymphs and Satyrs cannot resist.  Hermes swears his allegiance to her and is bound to her.  She and Geraldine are in a way sisters.  They both have an unnatural and supernatural command over men. I think Lamia's power is greater than Geraldine's because mythical creatures and Gods are held to a higher standard than a mere mortal. The fact that Lamia can bewitch them so easily is proof of her greater power.
