Among trials of individual animals for special acts of turpitude, one of the most amusing was that of a sow and her six young ones, at Lavegny, in 1457, on a charge of their having murdered and partly eaten a child. … The sow was found guilty and condemned to death; but the pigs were acquitted on account of their youth, the bad example of their mother, and the absence of direct proof as to their having been concerned in the eating of the child.

— Robert Chambers, The Book of Days, 1864
