Hi Mark S. I am. "The Art Of Memory" by Frances Yates is a favourite social history book of mine that puts it in context. Its very likely that the associative systems for memory by "loci" actually emerged from simple body part enumeration systems.
Its a rich legacy oral cultures bequeathed us. And early thinkers about what would eventually become the internet derived many of their concepts from the "arts of memory". BTW, you probably don't remember this thread :-) ... https://groups.google.com/forum/#!msg/tiddlywiki/Q4yLWNn5CKs/YVxdHp9_BgAJ in which you wrote interesting things.
