Yemen: An alabaster head, 3rd-1st centuries BCE, Arabia felix (Southern Arabia)

South Arabia as a general term refers to several regions as currently recognized, in chief the Republic of Yemen; yet it has historically also included Najran, Jizan, and 'Asir which are presently in Saudi Arabia, and Dhofar presently in Oman. The frontiers of South Arabia as linguistically conceived would include the historic peoples speaking the related South Arabian languages as well as neighboring dialects of Arabic, and their descendants. Anciently there was a South Arabian alphabet, which was borrowed by Ethiopia. South Arabia as generally conceived would include the lands inhabited by peoples partaking of its distinctive traditions and culture, which overlap recently demarcated political boundaries.
