Tablets of Astrology and Omens in the Royal Library of Nineveh
by Estéban Trujillo de Gutiérrez
“When Assurbanipal, king of Assyria, b.c. 668-626, added to the royal library at Nineveh, his contribution of tablets included many series of documents which related exclusively to the astrology of the ancient Babylonians, who in turn had borrowed it with modifications from the Sumerian invaders of the country.
Among these must be mentioned the Series which was commonly called The Day of Bel, and which was declared by the learned of the time to have been written in the time of the great Sargon I, king of Agade, c. 3800 B.C.
With such ancient works as these to guide them, the profession of deducing omens from daily events reached such a pitch of importance in the last Assyrian Empire, that a system of making periodical reports came into being, and by these the king was informed of all occurrences in the heavens and on the earth, and the results of astrological studies in respect to future events. The heads of the astrological profession were men of high rank and position, and their office was hereditary (see Diod., II, 29).

The variety of the information contained in these reports is best gathered from the fact that they were sent from cities so far removed from each other as Assur in the north and Erech in the south, and it can only be assumed that they were dispatched by runners or men mounted on swift horses.
As reports also come from Dilbat, Kutha, Nippur and Borsippa, all cities of ancient foundation, the king was probably well acquainted with the general course of events in his empire.”
