Belshazzar

Bel protect the king!, the last of the kings of Babylon (Dan.
5:1). He was the son of Nabonidus by Nitocris, who was the
daughter of Nebuchadnezzar and the widow of Nergal-sharezer.
When still young he made a great feast to a thousand of his
lords, and when heated with wine sent for the sacred vessels his
"father" (Dan. 5:2), or grandfather, Nebuchadnezzar had carried
away from the temple in Jerusalem, and he and his princes drank
out of them. In the midst of their mad revelry a hand was seen
by the king tracing on the wall the announcement of God's
judgment, which that night fell upon him. At the instance of the
queen (i.e., his mother) Daniel was brought in, and he
interpreted the writing. That night the kingdom of the Chaldeans
came to an end, and the king was slain (Dan. 5:30). (See
NERGAL-SHAREZER T0002709.)

The absence of the name of Belshazzar on the monuments was
long regarded as an argument against the genuineness of the Book
of Daniel. In 1854 Sir Henry Rawlinson found an inscription of
Nabonidus which referred to his eldest son. Quite recently,
however, the side of a ravine undermined by heavy rains fell at
Hillah, a suburb of Babylon. A number of huge, coarse
earthenware vases were laid bare. These were filled with
tablets, the receipts and contracts of a firm of Babylonian
bankers, which showed that Belshazzar had a household, with
secretaries and stewards. One was dated in the third year of the
king Marduk-sar-uzur. As Marduk-sar-uzar was another name for
Baal, this Marduk-sar-uzur was found to be the Belshazzar of
Scripture. In one of these contract tablets, dated in the July
after the defeat of the army of Nabonidus, we find him paying
tithes for his sister to the temple of the sun-god at Sippara.
