Romans used it to suspend jars of olive oil to avoid breakages in slave galleys when the seas were rough, and called it the Amphora Knot.
Bootleggers during prohibition used it for bourbon when the cops chased them, and called it the Jug Knot.
In the UK, it is a Bottle Knot, and was used in shipyards and mines to smuggle something warming into the workplace, slung inside your coat so your pocket did not bulge. Sailors used it on their kit-bags, so it is also the Bag Knot.
