The next creature in the series comes from the middle ages. The cockatrice first appears around the 12th century. Early accounts describe the creature as a winged dragon or serpent with the head and legs of a rooster. The beast was said to be created when a rooster egg was hatched by a toad or a snake. This mixture of male egg and reptile care imbued the cockatrice with a glare that could turn living creatures to stone and venomous breath. The only creatures known to be able to kill a cockatrice were weasels, who were somehow immune to the creature's death stare. Other means of dispatching a cockatrice were to force it to listen to a rooster crowing or to make it look into a mirror.
The cockatrice legend is fairly limited in distribution. By the Enlightenment, the legend seems to have all but died out. Interestingly, the legend partially lives on in the form of the basilisk. In many early texts - and even the King James Bible - cockatrice, basilisk, and viper were used interchangeably. It's not clear how a dragon-rooster hybrid and a viper were the same, but the term cockatrice seems to have been used for any dangerous slithery creature.
