Some speculation on the Damkhiyyat, a strain of horses from 1333 CE

The Damkhiyyat (feminine singular Damkhiyyah, masculine singular Damkhi) are most likely a reference to Damkh, a mountainous range in Najd and its surrounding area (photo below). It lies some 300 km west of Riyadh, by Halban, on the highway from Riyadh to Mecca. Arab geographers and poets starting from the 700s CE alike made several references to the waterfalls and lush grazing pastures of this area. It was historically the territory of the tribe of Banu ‘Amru bin Kilab.
