He also has a dream in which he visits the Underworld. The Assyrian king Ashurnasirpal II (reigned 883–859 BC) built a temple to Mamu, possibly the god of dreams, at Imgur-Enlil, near Kalhu. The later Assyrian king Ashurbanipal (reigned 668– 627 BC) had a dream during a desperate military situation in which his divine patron, the goddess Ishtar, appeared to him and promised that she would lead him to victory. The Babylonians and Assyrians divided dreams into "good," which were sent by the gods, and "bad," sent by demons. A surviving collection of dream omens entitled "Iškar Zaqīqu" records various dream scenarios as well as prognostications of what will happen to the person who experiences each dream, apparently based on previous cases. Some list different possible outcomes, based on occasions in which people experienced similar dreams with different results. Dream scenarios mentioned include a variety of daily work events, journeys to different locations, family matters, sex acts, and encounters with human individuals, animals, and deities. The oldest oneirocritic manuscript hitherto discovered is the "Ramesside dream-book" now in the British Museum. A unique exemplar of a book of dream-interpretation from pre-Hellenistic Egypt, the surviving fragments were translated into English by Kasia Szpakowska. Between the paws of the Sphinx, there is a stele describing how Thutmose IV restored the Sphinx as a result of a dream, on the promise of becoming a pharaoh. Dream divination was a common feature of Greek and Roman religion and literature of all genres. Aristotle and Plato discuss dreams in various works. The only surviving Greco-Roman dreambook, the Oneirocritica, was written by Artemidorus. Artemidorus cites a large number of previous authors, all of whom are now lost. These include Artemidoros, Astrampsychos, Nikephoros, Germanos, and Manuel Palaiologos. The pertinent material is included in the several Purāṇa-s, such as the "Liṅga Purāṇa". Here, dreams about specific numbers or about reading specific chapters of the Qurʼan are among the chief subjects of prognostication. The most renowned of the Arabic texts of oneiromancy is the Great Book of Interpretation of Dreams, a 15th-century compilation of earlier scholarship.
