Alexander had planned to settle Greek colonists in Bahrain, and although it is not clear that this happened on the scale he envisaged, Bahrain became very much part of the Hellenised world: the language of the upper classes was Greek (although Aramaic was in everyday use). Local coinage shows a seated Zeus, who may have been worshiped there as a syncretised form of the Arabian sun-god Shams.  Tylos was also the site of Greek athletic contests.
