Sanaa

The first known text in the Musnad script that mentions Sanaa dates back to the 5th century BCE and it is mentioned as ṣnʿw, which is derived from the Sabaic word maṣna'a "fortress."

The city of Sanaa was founded by the Kingdom of Saba in the 1st century CE as a secondary capital, with the primary capital since the origins of the civilisation being at the oasis of Marib. The name Sanaa is probably derived from the Sabaic root ṣnʿ, meaning "well-fortified". The name is attested in old Sabaean inscriptions, mostly from the 3rd century CE, as ṣnʿw.

To the east and west, the Sanaa plain is bordered by cliffs and mountains, with wadis coming down from them. The northern part of the area slopes gently upward toward the district of Arhab, which was historically known as al-Khashab.

The southern part of the plain straddles the watershed between the al-Kharid and the Wadi Siham, which flows southwest towards the Yemeni Tihama. …
