Soqotra, is a small archipelago of four islands in the Indian Ocean.
The largest island, also called Socotra, is about 95% of the landmass of the archipelago. It lies some 240 kilometres (150 mi) east of the Horn of Africa and 380 kilometres (240 mi) south of the Arabian Peninsula.
The island is very isolated and a third of its plant life is found nowhere else on the planet. It has been described as the most alien-looking place on Earth. The island measures 132 kilometres (82 mi) in length and 49.7 kilometres (30.9 mi) in width.
There was initially an Oldoway (or Oldowan) culture in Socotra. Oldoway stone tools were found in the area around Hadibo by V.A. Zhukov, a member of the Russian Complex Expedition in 2008.
Socotra appears as Dioskouridou ("of Dioscurides") in the Periplus of the Erythraean Sea, a 1st-century AD Greek navigation aid. A recent discovery of texts in several languages, including a wooden tablet in Palmyrene dated to the 3rd century AD, indicate the diverse origins of those who used Socotra as a trading base in antiquity.
