Belshazzar in the Nabonidus Records בלשאצר בכתובות נבוניד
Two Babylonian documents in the British Museum that restored Belshazzar to history. The Nabonidus cylinder from Ur (BM 91125, Room 55; found by J.G. Taylor in the ziggurat, 1854, one of four) closes with the king's prayer for himself "and for Belshazzar, my firstborn son" — the figure once dismissed as Daniel's fiction, in his father's own foundation text. The Nabonidus Chronicle (BM 35382; purchased 1879, first translated 1924) records the king's years-long absence at Tayma while "the crown prince" governed in Babylon — and the city taken without battle in 539 BCE. Between them, the classic resolution of Daniel 5's puzzles: why Belshazzar is the king in the city, and why the reward on offer is third ruler.

Why it matters
For centuries, Daniel 5 carried two famous puzzles. Its king of Babylon on the night the city fell is Belshazzar — a name no Greek historian knew, and the king lists give Nabonidus. And the reward Belshazzar offers Daniel is oddly specific: to rule "as third" in the kingdom. Then Babylonia's own documents surfaced. A foundation cylinder from Ur ends with Nabonidus praying for "Belshazzar, my firstborn son"; the court chronicle shows Nabonidus absent for years at Tayma while the crown prince ran Babylon — a first and a second ruler, with third place the highest gift left to give — and records the city taken without battle on a single autumn night in 539. The man dismissed as fiction turned out to be filed under his father's paperwork, and the strange arithmetic of the story turned out to be the sharpest thing in it — the cast and the night of Daniel 5, from Babylonian clay.

|---|---|---|---|
| The Nabonidus cylinder from Ur — one of four found by J.G. Taylor in the ziggurat's foundation in 1854; exemplar BM 91125, displayed in Room 55 — records Nabonidus's restoration of the ziggurat of Sin and closes with his prayer for long life and right conduct for himself "and for Belshazzar, my firstborn son, the offspring of my heart." | archaeology external | ★★★★★ | |
| The Nabonidus Chronicle (BM 35382; from Babylon, purchased by the British Museum in 1879, first fully translated 1924) reports year after year that the king was in Tayma while "the crown prince, the officials, and the army were in Akkad," the New Year festival suspended in his absence — and, for 539 BCE, that "the army of Cyrus entered Babylon without battle."
The surviving tablet is a later archival copy (commonly placed in the later Persian or Seleucid era); the chronicle tradition it copies is treated as drawing on contemporary records. Interpretive debates within the text — e.g. the year-9 campaign line sometimes read as Lydia — do not touch the claims used here.

| Daniel 5 has Belshazzar as the king holding the feast on the night Babylon fell — killed "that very night," the kingdom passing to Media and Persia — and the reward he twice offers is to rule "as third (talta) in the kingdom." With Nabonidus first and Belshazzar second, third ruler is precisely the highest place a co-regent crown prince could bestow; and the chronicle's bloodless capture matches the feast-night surprise. This is the classic resolution of the chapter's puzzles — a historical convergence, stated as reconstruction rather than as the chapter's own words, since Daniel names Belshazzar's father as Nevuchadnetzar (on the usual harmonization, an ancestral or throne-line usage).
The co-regency reading of "third ruler" is the standard resolution and remains an inference; the attestation of Belshazzar as crown prince and de facto regent is not in dispute.

| Placement: the cylinder is placed at its composition (c. 540 BCE ≈ 3388 AM on the atlas's anchor for Bavel's last years); the chronicle, composed and copied later than the events it records, follows the atlas's standing rule — the artifact sits at its composition era, and the witnessed dates (556–539 BCE, ending at the fall of Babylon, 3389 AM) are carried in the claims. The entity's span, 3388–3390 AM, closes at Koresh's first year (Return to Zion).
Placement interpretation documented per the atlas rule for chronicles composed or copied later than the events they record.
