What happens

This chapter describes the mythical basilisk, or cockatrice, as the king of serpents, endowed with a crown-like crest and deadly powers including burning, petrifying looks, and lethal breath. It recounts ancient and medieval beliefs about its origin from a cock's egg hatched under a toad, its enmity with the weasel and the cock, and its use in temples. The chapter also references Pliny, Lucan, Shakespeare, and Shelley, and critiques the credulity of earlier naturalists like Aldrovandus.
