A lot of Bruno's memory palaces are very hard to use and require a strong knowledge of church latin. I only studied classical latin in my school days and find it very different to use books like On the Shadows of Ideas. If you really want to use a vintage memory palace I would recommend Phoenix by Peter of Ravenna.
I created my own memory palace that was based on the ptolemaic tree of life. You can find modern memory books that are way better.
