Here are some related symbols you may find interesting. The first one is from the aforementioned Fergus Hall deck, which I'm posting because it's somewhat reminiscent of Ryden's style.
This is the one I want you to look at. It's from Scapini's deck patterned after an old 14th century Itallian deck. This image contains a lot of additional symbols that amplify the central image of the hanged man. For instance, the coins falling from the pockets denote renunciation of materialism.
The lower right corner of the above card is shown here. It shows a slaughtered lamb and the alchemical symbol of the pelican tearing its own breast to feed its young.
