Records indicate that the audit shows up in civilizations of ancient Greece, China and Egypt, as financial documentation and regulations were needed while conducting business. Though not thoroughly documented, Grecian practices mimicked those of today. Circa 522-486 A.D. revealed an example of the first auditors working as the spies of King Darius of ancient Persia. These individuals were auditing by command from the King and to keep track of the business of the governors in ancient Persian territories. In 1494, Luca Pacioli published the first book on accounting in Venice, Italy, which showcased double entry accounting systems of the merchants of the time.
