The Assyrians derived their historical writing, as they did so many other cultural elements, from the Babylonians. In that country, there had existed from the earliest times two types of historical inscriptions. The more common form developed from the desire of the kings to commemorate, not their deeds in war, but their building operations, and more especially the buildings erected in honor of the gods. Now and then we have an incidental reference to military activities, but rarely indeed do we find a document devoted primarily to the narration of warlike deeds. Side by side with these building inscriptions were to be found dry lists of kings, sometimes with the length of their reigns, but, save for an occasional legend, there seem to have been no detailed histories. It was from the former type that the earliest Assyrian inscriptions were derived. In actual fact, we have no right to call them historical in any sense of the word, even though they are our only sources for the few facts we know about this early period. A typical inscription of this type will have the form "Irishum the vice gerent of the god Ashur, the son of Ilushuma the vice gerent of the god Ashur, unto the god Ashur, his Lord, for his own life and for the life of his son has dedicated". Thus there was as yet little difference in form from their Babylonian models and the historical data were of the slightest. This type persisted until the latest days of the Assyrian empire in the inscriptions placed on the bricks, or, in slightly more developed form, in the inscriptions written on the slabs of stone used for the adornment of palace or temple. For these later periods, they rarely have a value other than for the architectural history, and so demand no further study in this place. Nevertheless, the architectural origin of the historical inscription should not be forgotten. Even to the end, it is a rare document which does not have as its conclusion a more or less full account of the building operations carried on by the monarch who erected it. It was not long until the inscriptions were incised on limestone. These slabs, giving more surface for the writing, easily induced the addition of other data, including naturally some account of the monarch's exploits in war. The typical inscription of this type, take, for example that of Adad nirari I, [Footnote: BM. 90,978; IV. R. 44 f.; G. Smith, _Assyr. Discoveries_, 1875, 242 ff.; Pognon, JA. 1884, 293 ff.; Peiser, KB. I. 4 ff.; Budge-King, 4 ff.; duplicate Scheil, RT. XV. 138 ff.; Jastrow, ZA. X. 35 ff.; AJSL. XII 143 ff.] has a brief titulary, then a slightly longer sketch of the campaigns, but the greater portion by far is devoted to the narration of his buildings. This type also continued until the latest days of the empire, and, like the former, is of no value where we have the fuller documents.
