Zabur is the name of the cursive form of the South Arabian script that was used by the ancient Yemenis (Sabaeans) in addition to their monumental script (or Musnad) (see, e.g., Ryckmans, J., Müller, W. W., and ‛Abdallah, Yu., Textes du Yémen Antique inscrits sur bois. Louvain-la-Neuve, 1994 (Publications de l'Institut Orientaliste de Louvain, 43)).
The cursivezabur script—also known as "South Arabian Minuscules"[2]—was used by the ancient Yemenis to inscribe everyday documents on wooden sticks in addition to the rock-cut monumental musnad letters displayed below.
