A sequence of omens has puzzled Assyriologists since 1866, when Henry C. Rawlinson published the first copy of these peculiar divinatory texts. The omens have the structure DIŠ MUL ana … GUR, “If a star turns into …”, where the object into which the star changes can be an animal, metal, stone or some other item. Such a change has been held to belong to the field of dreams or, more generally, to terrestrial events rather than to astronomy. In fact, however, these omens refer to a specific celestial phenomenon, the transformation of a “star” into a meteorite that can be picked up from the ground, as can also be seen in the phrasing of the corresponding namburbi-ritual, which some scribes appended to their recension of this omen sequence.
