Described By: Unknown- "For they say that when a Cocke groweth old, he layeth a certaine egge without any shell, instead whereof it is covered with a very thicke skinne, which is able to withstand the greatest force of an easie blow or fall. They saye, moreover, that this egge is layd onely in the Summer time, about the beginning of the Dogge-dayes (between early July and early September), being not so long as a Hens Egge, but round and orbiculer:...sometimes of a yellowish muddy color... and afterward sat upon by a Snake or Toad, bringeth forth the Cockatrice, being halfe a foot in length, the hinder part like a snake, the former part like a Cocke, because of a treble comb on his forehead."
Supposedly there was a cockatrice found in the vault of a chapel dedicated to Saint Lucea during the time of Pope Leo the Fourth (847 to 855.) The breath of this cockatrice fouled the air, and caused many deaths in Rome.
