Somewhere back in 13th century france, there lived a knight who had a greyhound. One day he went hunting, and left his newborn son to be watched over by the dog. When he came home, he found the room in chaos, the cot overturned, and the dog with blood on his jaws.
Horrified, he drew his sword and slew the beast.
Then he heard the wails of his child...Under the overturned cot the boy lay unhurt, along with the blooded body a poisonous viper, killed by Guinefort, the faithful dog.
Guilt struck, he dropped de dog in a well in a forest, and on this place a peculiar cult sprung up.
Parents would leave sickly children they believed to be changelings here, hoping for their real children to be returned. This did not always end well and the official church tried to end the worship. But in spite of this, the dog saint cult persisted well into the 20th century.
This is part 2 of a 7 part series of lino cuts of unusual saints. I didn't make these up, they are all real "people's" saints, though not all of them approved by "Rome". I'm afraid the scanner isn't doing them any favours.
And by the way, I'm not catholic, I'm just having an interest.
