Oil and petroleum products have been in use for centuries, beginning in the Middle East. The Greek historian Herodotus described the presence of oil pits in Babylon, present day Iraq, in 450 B.C. Alexander the Great often used oil-fueled torches to frighten his enemies. Another Greek historian, Plutarch, described oil bubbling up from the ground in Kirkuk.
Oil was not only found in the Middle East, but in China as well. In 347 A.D., the Chinese were using bamboo to drill oil from the ground. Explorer Marco Polo described the Baku people, in present day Azerbaijan, using oil from seeps for lighting and medicine.
Oil has a long history in America; early explorers to the area observed oil slicks off the coast of California.
