Fascinating to read the priest's account.
He sounds like a more down-to-Earth man than some of his parishioners.
The proliferation of acorns, presumably attracted deer, wild pigs, squirrels and other rodents to the vicinity, which in turn attracted "predatory wolves". I liked curé Favre's scathing words that "the common populace believe the beasts to be werewolves and nothing will change their foolish credulity."
The French Wiki site links to similar accounts from south-east France from around the same time of the beast of Gévaudan and beast of Lyonnais, both of which seem very wolf-like although, in the first case, is described as having unnaturally long legs.
