2,000-year-old artefact at the national museum

Oman’s National Museum has added a 2,000-year old artefact - a tripartite stone - to its collection.
The tripartite stone can be found along the coastal area of the Southern and Eastern Arabian Peninsula, from Hadramout in Yemen to Ras al-Hadd in Oman.
The triangular stone formations are associated with a large circular fire drill dating back to the Late Iron Age.
These formations consist of three vertical flat stones that form a little pyramid, often arranged in rows on the sides of dry waterways and old trade routes.
