The Memory Palace is a kind of memory technique, as well as a book.
This book is also known as "Lima's Memory Palace," and it describes a rational memory method that has existed for a long time.
As for the origins of this memory method, there are many opinions. In fact, one says it comes from Ancient Rome, being a secret technique not passed down among a few great scholars. Precisely by mastering this method, the great scholars can acquire wisdom far beyond ordinary people.
Another theory says it comes from Ancient Greece, supposedly originating from the Greek poet Simonides. One day, Simonides recited a hymn in the grand banquet hall and left for some reason. Then the hall suddenly collapsed, and all guests inside perished, their bodies blurred and indistinguishable. Simonides, who survived, calmly analyzed based on the guests' positions in the hall, identifying the bodies one by one. His ability shocked many, and eventually, under pressure, he revealed the secret of his memory.
