It was during his excavations in the foundations of the Sun temple at Larsa that he came upon a cylinder inscribed and deposited by Hammurabi, or Khammuragas, at the rebuilding of a more ancient temple on the same site.
Hammurabi states upon his cylinder that this more ancient temple was founded by Urea, or Ur Gur, seven hundred years before his time.
On annalistic tablets of Babylonian kings in the British Museum, Khammuragas is mentioned and the date accorded to him B. C. 2315, or the end of his reign B. C. 2259, which gives the date of Urea, The Builder, as about 2959 B. C.
The most important of the discoveries of Nabonidus, was, however, the finding of the foundation cylinder of Naram-Sin, the son and successor of the great Sargon of Accad.
This occurred at the time of his restoration of the Sun temple at Sippara, near the ancient city of Agane.
Of this, Nabonidus says:
“I brought the Sun God from his temple, and placed him in another house.”
“I sought for its old foundation stone, and eighteen cubits deep—”
“I dug into the ground and the foundation stone of Naram-Sin, Son of Sargon, which for thirty-two hundred years no king who had gone before me had seen.”
“The Sun God—the great Lord of E Bara. Let me see; even me.”
