The Book of the Dun Cow

Chauntecleer is a rooster who runs the chicken coop in a time before humans were on Earth, an ordinary rooster, brave but also proud. He is befriended by the sad and mournful dog, Mundo Cani. Chauntecleer meets and marries a lovely hen with a beautiful voice, Pertelote. Pertelote is a refugee from a nearby coop run by the mad rooster Cockatrice, and Cockatrice, guided by the evil Wyrm, a worm who lives inside Earth, plans to go to war against the other animals. It is up to Chauntecleer to stop Wyrm and his henchman, Cockatrice, and so the war begins.

The Book of the Dun Cow is a complex story that weaves in elements of Christianity as well as Celtic mythology.
