Gates of horn and ivory
Literary image, originally from Greek
The gates of horn and ivory are a literary image used to distinguish true dreams (corresponding to factual occurrences) from false. The phrase originated in the Greek language, in which the word for "horn" is similar to that for "fulfill" and the word for "ivory" is similar to that for "deceive" (see Murray, below). On the basis of that play on words, true dreams are spoken of as coming through the gates of horn, false dreams as coming through those of ivory.
The Odyssey
The earliest appearance of the image is in the Odyssey, book 19, lines 560–569. There Penelope, who has had a dream that seems to signify that her husband Odysseus is about to return, expresses by a play on words her conviction that the dream is false. She says:
Stranger, dreams verily are baffling and unclear of meaning, and in no wise do they find fulfillment in all things for men. For two are the gates of shadowy dreams, and one is fashioned of horn and one of ivory. Those dreams that pass through the gate of sawn ivory deceive men, bringing words that find no fulfillment. But those that come forth through the gate of polished horn bring true issues to pass, when any mortal sees them. But in my case it was not from thence, methinks, that my strange dream came.

Why this record matters
The phrase “literary image, originally from Greek” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Attribution, date and provenance are strongest when supported by the original work, a catalogue record and documented transmission. The source revision retrieved here is dated Aug 15, 2026. The linked authority identifier is Q3909015. None of the 0 selected statements returned an explicit reference.
Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
