The Greek historian Strabo believed the Phoenicians originated from Bahrain. Herodotus also believed that the homeland of the Phoenicians was Bahrain. This theory was accepted by the 19th-century German classicist Arnold Heeren who said that: "In the Greek geographers, for instance, we read of two islands, named Tyrus or Tylos, and Aradus, which boasted that they were the mother country of the Phoenicians, and exhibited relics of Phoenician temples." The people of Tyre, in particular, have long maintained Persian Gulf origins, and the similarity in the words "Tylos" and "Tyre" has been commented upon. However, there is little evidence of any human settlement at all on Bahrain during the time when such migration had supposedly taken place.
