With Enannatum II., the son of Entemena, who succeeded his father upon the throne, the dynasty founded by Ur-Ninâ, so far as we know, came to an end.[21] The reign of Entemena's son is attested by a single inscription engraved upon a door-socket from the great store-house of Ningirsu at Lagash, his restoration of which is recorded in the text. There then occurs a gap in our sequence of royal inscriptions found at Tello, the next ruler who has left us any records of his own, being Urukagina, the ill-fated reformer and king of Lagash, under whom the city was destined to suffer what was undoubtedly the greatest reverse she encountered in the long course of her history. Although we have no royal texts relating to the period between the reigns of Enannatum II. and Urukagina, we are fortunately not without means for estimating approximately its length and recovering the names of some, if not all, of the patesis who occupied the throne of Lagash in the interval. Our information is derived from a number of clay tablets, the majority of which were found in the course of native diggings at Tello after M. de Sarzec's death.[22] They formed part of the private archive of the patesis of Lagash at this time, and are concerned with the household expenses of the court and particularly of the harîm. Frequently these tablets of accounts make mention of the reigning patesi or his wife, and from them we have recovered the names of three patesis--Enetarzi, Enlitarzi, and Lugal-anda[23]--who are to be set in the interval between Enannatum II. and Urukagina. Moreover, it has been pointed out that the inscriptions upon most of the tablets end with a peculiar form of figure, consisting of one or more diagonal strokes cutting a single horizontal one; and a plausible explanation has been given of these figures, to the effect that they were intended to indicate the date of the tablet, the number of diagonal strokes showing at a glance the year of the patesi's reign in which the text was written, and to which the accounts refer. A considerable number of such tablets have been examined, and by counting the strokes upon them it has been concluded that Enetarzi reigned for at least four years, Enlitarzi for at least five years, and Lugal-anda for at least seven years.[24]
