 Other variations occur, and some of the Latin phrases have been interpreted differently. For example, in his early work De Inventione, Cicero says the criminal's mouth was covered by a leathern bag, rather than a wolf's hide. He also says the person was held in prison until the large sack was made ready, whereas at least one modern author believes the sack, culleus, involved, would have been one of the large, very common sacks Romans transported wine in, so that such a sack would have been readily available. According to the same author, such a wine sack had a volume of 144.5 US gallons (547 l).
