The Ancient South Arabian Script is a writing system used in the southern Arabian Peninsula, primarily by the kingdoms of Saba, Hadramaut, and Qataban. This script dates back to around the 8th century BCE and is characterized by its unique characters, which are distinct from other Semitic scripts. It was mainly used for inscriptions on stone, pottery, and other materials. This script consists of 29 letters and is written from right to left. It played a crucial role in documenting the languages spoken in the region, such as Sabaean and Hadrami. The Ancient South Arabian Script is an important part of the cultural heritage of Yemen and provides insights into the history and society of ancient Arabian civilizations.
