Sennacherib says he shut Hezekiah up like a bird in a cage. The phrase is everywhere. Almost nobody who quotes it says which prism they are quoting, which translation, or from what century.
The problem, stated on one example
Search for Sennacherib and Hezekiah and you will find the caged-bird line reproduced thousands of times. Very few of those reproductions say which object the text is on. Fewer say which edition the translation comes from. A great many are copies of copies.
This study follows that one sentence backwards, because the exercise is more useful than the sentence.
Step one: which object
The inscription survives on several clay prisms, not one. The best known in English-speaking contexts is the Taylor Prism in the British Museum, but the same composition is on other exemplars in other collections, and the exemplars are not identical.
This matters more than it sounds. A citation that says the Sennacherib prism is naming a genre, not an object. A citation that gives a catalogue number can be checked; one that does not, cannot.
There is a live trap here that this site walked into and recorded. A major cuneiform database labels one exemplar with the popular name Taylor Prism in its designation field — but that record’s museum number belongs to a prism in Chicago, not the one in London. The label was right about the text and wrong about the object. Only comparing catalogue numbers caught it.
Step two: which translation
Most freely available English renderings of the Assyrian annals trace back, directly or at several removes, to a translation published in 1927. It was competent work and it is out of copyright, which is why it circulates.
It has also been superseded. The corpus has since been re-edited from collated originals, with better readings and with the differences between exemplars set out. Where a figure or a phrase matters to an argument, the modern edition is the one to use.
A reader who does not know which translation they are reading cannot know whether a variant they have noticed is a variant in the ancient text or a difference between translators.
Step three: which claim rests on it
The caged-bird phrase is usually deployed to make a point about Jerusalem not being captured. It will support that point, carefully: the inscription describes confinement and tribute and does not claim the city.
It will not support the stronger point it is often made to carry — that Sennacherib is conceding a failure. Royal inscriptions do not narrate failures, and a campaign that ends in tribute is reported as a success in that genre. The silence is generic, not confessional.
Why this is a method study and not a footnote
Every claim on this site depends on a chain of the same three links: an object, an edition, and a use. This archive publishes the first two for every source it cites, with a permanent identifier that a stranger can follow, and re-tests them on a schedule.
That is a narrower promise than most sites in this field make, and it is the only one that can be checked.
