Archeology had its start in the European study of history and in people who were interested in the past. King Nabonidus (556-539 BCE), the last king of the Neo-Babylonian Empire, was interested in the past so he could align himself with past glories. He led a revitalization movement and rebuilt ancient temples. Even back in what one would think was ancient times itself there was the start of the systematic investigation into the past by Herodotus (c. 484-c. 425). He was the first western scholar to systematically collect artifacts and test their accuracy. He was also the first to make a compelling narrative of the past. He is known for his set of 9 books called The Histories, in which he wrote of everything he could find out about different regions. A few examples are he discussed the causes and consequences of the Greco-Persian Wars. He also explored the Nile and Delphi. However, scholars have found errors in his records and believe he probably did not go as far south down the Nile as he said he did.
