This document provides a history of ideas and theories about memory from ancient Greece to the 17th century. The Greeks were the first to propose physical, rather than spiritual, bases for memory and developed concepts of association of ideas. The Romans contributed link and room memory systems. Galen located memory in the brain and nerves in the 2nd century AD. For over 1500 years after, the Church suppressed new ideas and doctrine dominated theories. Progress resumed in the 17th century, though still restricted by doctrine.
