But the scientific impulse of ancient Accad remained an impulse only, the methods of science were undiscovered, and the student was led astray by his own fancies and misconceptions; still amidst all the false science of a primitive Chaldea there were germs of truth, which have been developed even in our own times. The classic writers said truly that Babylonia was the birthplace of astronomy. It was also the birthplace of mathematics; and although their figures were simple, the Chaldeans attained quite a proficiency in their calculations. The library at Larsa or Senkereh was famous for its mathematical works, and it formed a nucleus for students from various portions the country. LITERATURE OF NINEVEH. On the banks of the Tigris, a great city lifted her battlements and arches towards the skies, and became the home of Assyrian Kings. According to Diodorus[5] her walls were an hundred feet high, and so broad that four chariots could be driven abreast upon them, while fifteen hundred towers, apparently impregnable, arose from their massive foundations. Nineveh was the home of imperial splendor, and twenty-two kings were taxed to supply the materials for her costly palaces where the finest sculptures of the East were found. Assyrian art covered her angles with graceful curves, and built her temples with their gilded domes, while the interior walls were adorned with sculptured slabs of white alabaster. The germs of Greek art, as well as Greek mythology, were found in the valleys of the Tigris and the Euphrates, for here were Doric and Ionic columns; here were Corinthian capitals, with architrave, frieze and cornice, and yet the latest of these must have been carved before the earliest date which has been assigned to any work of Grecian art. Though her culture was confined to certain classes, and the great mass of her population could not discern between their right hands and their left, still, for centuries Nineveh[6] was the mistress of the East, even Babylon being subject to her power.
