It was discovered in 1961 in the Amman Citadel, and first published in full in 1968 by Siegfried Horn.

[4] The size and shape of individual letters vary considerably, suggesting that the inscription comes from a novice scribe.

Numerous letters have unusual shapes, for example the ḥēt has only two cross beams, compared to the usual three (𐤇‎), similar to the Mesha stele.

The ṭēt is only a crossbar in a circle (instead of the usual 𐤈‎), and the ʿayin is already slightly open upwards (𐡏‎ instead of 𐤏‎), which occurs in Phoenician inscriptions only from the 5th century.

The reconstruction by William Fulco assumes that the inscription concerns the Ammonite chief deity Milcom, restoring a single missing letter to form the name.
