about Cicero exploring techniques for improving memory such as the "walk-through-the-house" (?) method
Method of loci - Wikipedia

The method of loci is a good example of an ancient cultural meme (for lack of a better term) that was available to everyone and all schools of philosophy. It seems many times these techniques or tools get associated with a particular school (many times the Stoics since that's the one that was acceptable or malleable or able to be appropriated by later authorities, ex, Christians), but that doesn't mean it's their proprietary tool or technique.
