In European bestiaries and legends, a basilisk (/ˈbæsɪlɪsk/ or /ˈbæzɪlɪsk/[1]) is a legendary reptile reputed to be a serpent king, who can cause death with a single glance. According to the Naturalis Historia of Pliny the Elder, the basilisk of Cyrene is a small snake, "being not more than twelve fingers in length",[2] that is so venomous, it leaves a wide trail of deadly venom in its wake, and its gaze is likewise lethal.
