Nearly 2,000 years later, a man in 15th-century Italy named Peter of Ravenna used the loci method to memorize books and poems.
He memorized religious texts, all of the laws of the time, 200 speeches, and 1,000 poems.
By using the loci method, was able to reread books stored in the "memory palaces" of his mind.
"When I [travel] I can truly say I carry everything I own with me," he wrote.
