Tylos

[4] The Greek geographer Strabo mentions islands in Persian Gulf named Tyre and Arad (Muharraq) and the local legend that they are the metropoleis of Phoenicians.

[11] During this period, Tylos was very much part of the Hellenised world: while Aramaic was in everyday use, the language of the upper classes was Greek.

Local coinage shows a seated Zeus, who may have been worshiped there as a syncretised form of the Arabian sun-god Shams.

[13] With the waning of Seleucid power, Tylos passed under the control of Mesene, the kingdom founded in what today is Kuwait by Hyspaosines in 129 BC, which ruled the island until second century AD.

[16] At some point Mesene ceased to be a sub-kingdom, and Bahrain was incorporated into the Sassanid province of Mazon covering the Persian Gulf's southern shore.
