For all gouts. Take an owl and pluck him and open him as you would to eat him, and salt him well and place him in an earthenware pot and put a tile thereon (i.e. over the mouth of the pot) and place it in a hot oven when men put in dough (i.e. for making bread), and when they bring it out, look whether the owl is ready to make powder from or else let it stand until he is.
Then, beat the owl to powder and temper it with boar's grease and anoint the sore (part of the body) with it (while sitting) by the fire.
