From the ancient Greeks to modern times, the art and science of memory training have been continually refined. The foundations of memory techniques can be traced back to the aborigines who used dream time stories to etch into their memories everything about the world they lived in and how to survive and this information they passed on from generation to generation.

Then came the great orators of classical Greece, such as Simonides of Ceos. They employed the "Method of Loci", which involved visualizing objects or information within familiar locations, such as rooms in a building or spots in a market, to better recall their speeches.

Fast forward to the Middle Ages, the "Ars Memorativa" or "Art of Memory" was a widely practiced technique among scholars and theologians. These methods entailed the use of intricate visual images and associations, turning abstract data into memorable and vivid imagery.

With the dawn of the modern era, there was a renewed interest in cognitive psychology and the mechanisms of memory. Researchers began to understand the intricacies of short-term and long-term memory, leading to techniques such as chunking and spaced repetition. Technologies like flashcards and later digital platforms like Anki and SuperMemo built upon these techniques, making memory training more systematic and efficient.

Today, in our information-driven age, memory training is not just for competitions or academic pursuits but has become a valuable skill for personal and professional development and is a must for survival as rate of change of technology outpaces human evolution. As we look back, it's evident that the essence of memory training remains the same: transforming the intangible into the tangible, making the forgotten unforgettable.
