The Jacob is a British breed of domestic sheep. It combines two characteristics unusual in sheep: it is piebald—dark-coloured with areas of white wool—and it is often polycerate or multi-horned. It most commonly has four horns. The origin of the breed is not known; broken-coloured polycerate sheep were present in England by the middle of the seventeenth century, and were widespread a century later. Among the many accounts of ancient breeds of piebald sheep is the story of Jacob from the first book of the Hebrew Bible, called by Christians the Old Testament. According to the Book of Genesis, Jacob took every speckled and spotted sheep from his father-in-law’s flock and bred them. Due to the resemblance to the animal described in Genesis, the Jacob sheep was named for the Biblical figure of Jacob sometime in the 20th century.
