Sankt Mattheus is the patron saint of those who love and care for animals.
Mattheus was a monk who was sent by the king to rid a town of a beast who was terrorizing and slaughtering the inhabitants of the town, after the hunters sent before could not find or kill the beast. Mattheus found a wolf in the forest in less than an hour and offered it salt fish and meat from his own hand. But because he was a holy man and beloved by the saints, the wolf did not devour him where he stood and ate from Mattheus' palm. He came into the forest every day to feed the wolf and its' pups, and because the wolves were well fed the killings stopped.
Mattheus continued to visit the pups and fed them until they were grown wolves themselves, with their own pups. They came when he called and thumped their tails when he told them stories. Their pups were tame in the same way and guarded the same doorways and hearths of the village their grandmother had once terrorized. They were the first dogs and the reason why Sankt Mattheus is the patron saint of those who love and care for animals.
