Cotytto, a Thracian goddess worshipped in particularly licentious rites, appears in Milton's Comus:
Goddesse of Nocturnal sport
Dark vaild Cotytto, t' whom the secret flame
Of mid-night Torches burns; mysterious Dame
That ne're art call'd, but when the Dragon woom
Of Stygian darknes spets her thickest gloom,
And makes one blot of all the ayr. [ll. 129-36; text transcribed by Judith Bass
