Taṯlīṯ
Tathlith lies in a long valley of southern Arabia, east of the Sarawat mountains. The wadi is named in Arabic geographical and literary works, and its rocks preserve inscriptions and drawings left by earlier inhabitants. Ancient mining remains in the district include small shafts associated with gold extraction. These workings link the valley to the mineral-bearing country of Bishah, Tabalah and Najran, where gold and iron were also known.
