Da Vinci was a painter, an engineer, a writer, a sculptor, an inventor, an architect, a pioneer in exploring human anatomy, an avid animal lover and possibly one of the most famous vegetarians (if not vegans) who ever lived. It seems that there’s nothing that this man did not do. Yet there was, it was sleeping. He wasn’t a fan of it and after conducting careful research and building up his knowledge, he started following the polyphasic sleep cycle. To put it in other words, Da Vinci’s sleep would consist of several short naps every 24 hours. Being The Renaissance man is not so easy.
