Petrarch lived in the late 12th Century. He decided to go camping in the mountains. So, he took 12 servants with him who set up camp for him. He came from a rich family and was ever curious about the world around him. He had his servants searched the known world for books, especially Greek philosophers. He went camping to catch up on his reading and to commune with nature. He observed nature and wrote about it with a scientist eye. Nearby was a rushing river. He listened to it for hours on end.
He came off that mountain a few weeks later with an enlightened mind. He continued his scientific researches, and studying the Roman and Greek writers. He also questioned the Church teachings, but was always a devout Christian. His poetry and other publications were read all over Europe and he helped start the Renaissance.
