All hail the king of the snakes! Basilisks—from the Greek basiliskos, for "little king," are depicted in many early modern natural histories and were said to be the kings of the serpents (Dark Arts students will recognize them for their diadem-shaped crests). J.K. Rowling preserves many details of the accounts from sixteenth- and seventeenth-century sources about this terrifying snake, including his birth from a chicken's egg hatched under a toad, and a gaze that could kill. Susceptible to wizard control by some Parselmouths, only Tom Riddle proved snake-charmer enough to ever challenge one.
