In European bestiaries and legends, a basilisk (from the Greek βασιλίσκος basiliskos, a little king, in Latin Regulus) is a legendary reptile reputed to be king of serpents and said to have the power of causing death by a single glance. According to the Naturalis Historia of Pliny the Elder, the basilisk is a small snake that is so venomous that it leaves a wide trail of deadly venom in its wake, and its gaze is likewise lethal. The rooster is deadly to the Basilisk.
