Medieval and Manuscripts
A cockatrice is a mythical beast, essentially a two-legged dragon, wyvern, or serpent-like creature with a rooster's head. Described by Laurence Breiner as "an ornament in the drama and poetry of the Elizabethans", it was featured prominently in English thought and myth for centuries. According to legend, they are created by a chicken egg hatched by a toad or snake.
