According to Garbini Ḥwkw is an attribute of Mārib, which merged various cities belonging to different tribes. This hypothesis is confirmed by the inscription Gl 1719-1717-1718, where the name of Mārib is followed by the proper name ḏ-Ṭs¹s¹m. Wissmann, instead, interprets Ḥwkw as the proper name of part of the Mārib wall.
1 Yṯʿʾmr Byn, son of S¹mhʿly, mukarrib of Sa‒
2 baʾ, surrounded with a wall Mryb Ḥwkw, when he founded all
3 the community, that of the god and Patron and of the territory and people.
The inscription was found in the village of al-Khobar, east of Ẓahran, stored in a private house. Wissmann suggests that most probably the text was originally placed on the city-walls of Mārib.
