Incorrectly asserted in Dan. 5: 2 to be the son of Nebuchadnezzar and last king of Babylon. Cuneiform inscriptions found at Ur, however, show that he was the son of Nabonidus of Babylon (556–539 BCE) and that he ruled as regent during the king's absence. The story in the book is of a feast given by Belshazzar during which a mysterious hand writes a legend of doom on the wall and he is slain that very night—a drama that has inspired many paintings and some great music (e.g. William Walton's oratorio).
