In the first millennium BCE, some scholars at Babylon were paid to keep careful record of events in heaven and earth in order to improve the accuracy of their astrological predictions. Books on the Achaemenid empire often devote a few pages to them, because they are so impressive. Aristotle and his students don’t seem to have managed anything which was at once as empirical and as quantitative, and they started at least 300 years later; a number of discoveries which were formerly attributed to Greek astronomers seem to have been made first in Babylonia and taught to Greeks in Alexander’s army. Some diarists kept daily records of the price of six basic commodities, for the movements of prices seemed just as majestic and uncontrollable as the movements of the planets or the birth of three-headed snakes. Babylonian scholars in the first millennium BCE were not given to writing long treatises on clay, but they were very good at collecting data and finding patterns. Historians of science seem to think that the combination of empirical success with a far-from-naturalistic worldview used to be common.
The astronomical diaries give us some of our few narratives from Mesopotamia after the fall of the Assyrian empire, and some of them mention military events such as these battles between the Babylonians and Assyrians. Like the Achaemenid royal inscriptions, they usually limit themselves to date, place, antagonists, and outcome rather than trying to explain how the two armies fought; unlike the royal inscriptions, they avoid explicit comment on the meaning of battles. Nevertheless, even these brief notes often mention events which the Greek sources do not, and ignore the ones which they do.
