Tylos

Tylos was the Greek name for Bahrain in the Hellenistic and Roman periods, first recorded by writers drawing on the voyages of Alexander the Great's officers. The island was known for its pearls and cotton and belonged to trade networks of the Seleucids and later of Characene and the Parthians. Archaeologists use the name for the Tylos period of Bahraini history, from about 300 BCE to 600 CE.
