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.
Herodotus also reports the
Tyrian tradition that Phoenicians originated in the Persian Gulf, and theory that the same pair of cities
Tyros/Tylos and
Arad in both Phoenicia and Persian Gulf may suggest colonization from one way or another has been much discussed. However, there is little evidence of occupation at all in Bahrain during the time when such migration had supposedly taken place. It is not known whether Bahrain was part of the
Seleucid Empire, although the archaeological site at
Qalat Al Bahrain has been proposed as a Seleucid base in the Persian Gulf. 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. Tylos also held Greek athletic contests. 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. A building inscription found in Bahrain indicates that Hyspoasines appointed a
strategos to rule the islands. Another king of Mesene
Meredates (r. 130–151 AD) from the
Parthian dynasty is also mentioned by an inscription to have Tylos governed by a satrap. In the third century AD, the Sassanids succeeded the Parthians as the suzerain of Mesene.
Ardashir, the first ruler of the
Sassanian dynasty conquered the area and give the kingdom to his son. Likewise, the son of
Shapur I was crowned the king of Mesene. 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. By the fifth century Bahrain was a centre for
Nestorian Christianity, with
Samahij having an episcopal see. In 410, according to the Oriental Syriac Church synodal records, a bishop named Batai was excommunicated from the church in Bahrain. It was also the site of worship of a shark deity called
Awal. Worshipers reputedly built a large statue to Awal in Muharraq, although it has now been lost, and for many centuries after Tylos, the islands of Bahrain were known as
Awal. ==References==
