Strabo, the Greek historian, geographer and philosopher mentioned that the Phoenicians came from Bahrain where they have similar gods, cemeteries and temples. 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 Arad, Bahrain, which boasted that they were the mother country of the Phoenicians, and exhibited relics of Phoenician temples". The people of Tyre, Lebanon in particular have long maintained Persian Gulf origins, and the similarity in the words "Tylos" and "Tyre" has been commented upon. Later classicist theories were proposed prior to modern archaeological excavations which revealed no disruption of Phoenician societies between 3200 B.C. and 1200 B.C.
