So below is an image cut from an illustration of soldiers from the Grande Armée of Napoleon. I thought I'd share as this shows the man suspending a pot using a stick (nothing new) which appears to be hanging from a rope. One could use a chain as a substitute for a rope, and IF one used some support ropes or chains, one could vary the height by slackening or tightening the rope/chain.
At least I think this is from a period illustration.....
