Some of the prayers were for use on special occasions, such as on starting on a campaign, on the occurrence of an eclipse, &c. Astronomy and astrology were represented by various detached inscriptions and reports, but principally by the great work of which mention has already been made, and many copies of which were in the Library of Assur-bani-pal. Among the Astrological tablets is a fragment which professes to be copied from an original of the time of Izdubar. Historical texts formed another section of the library, and these included numerous copies of inscriptions of early Babylonian kings; there were besides, chronological tablets with lists of kings and annual officers, inscriptions of various Assyrian monarchs, histories of the relations between Assyria and Babylonia, Elam, and Arabia, treaties, despatches, proclamations, and reports on the state of the empire and military affairs. Natural history was represented by bilingual lists of mammals, birds, reptiles, fishes, insects, and plants, trees, grasses, reeds, and grains, earths, stones, &c. These lists are classified according to the supposed nature and affinities of the various species, and show considerable advance in the sciences. Mathematics had a place in the library, there being tables of problems, figures, and calculations; but this branch of learning was not studied so fully as in Babylonia. Grammar and Lexicography were better represented, since there were many works on these subjects, including lists of the characters, the declension of the noun, the conjugation of the verb, examples of syntactical construction, reading-books, interlinear translations of Accadian texts, and the like. All these tablets were copied from Babylonian originals. In legal and civil literature the library was also rich, and the tablets serve to show that the same laws and customs prevailed in Assyria as in Babylonia. There are codes of laws, law cases, records of sale, barter, and loans, lists of property, lists of titles and trades, of tribute and taxes, &c. In Geography the Assyrians were not very advanced; but there are lists of countries and their productions, of cities, rivers, mountains, and peoples.
