Scripture: Daniel 5; Daniel 7:1

Belshazzar holds a feast in Babylon and sees the writing on the wall the night the city falls.
For a long time Belshazzar was known only from Daniel, and critics treated him as fictional. Cylinders of King Nabonidus found at Ur in 1854 name Belshazzar as his eldest son, and other texts say Nabonidus entrusted the kingship to him while he spent years in Arabia.
