Driving a chariot in the Shang and Zhou dynasties was serious business. Generally led by a team of four horses and surrounded by troops, chariots were the mainstay of military strategy; so much so that charioteering is one of the 'Six Arts' listed in the Book of Zhou (周禮, 2nd century BCE). A later commentator laid out the list though, as we shall see, quite a bit of guesswork is needed to decipher the items.
