I’m curious about why people are attracted to memory techniques. Does every person do the techniques for different reasons or are there similarities?
Here is a fascinating webpage about Giordano Bruno’s memory system.
Frances Yates reconstructed Bruno’s mnemonic wheel based on his book De Umbris Idearum. De Umbris Idearum can be downloaded here. Unfortunately, I’ve only seen it available in Latin so haven’t been able to read it.
