During the Achaemenid period (c. 550‒330 BC), the bay of Kuwait was repopulated after seven centuries of abandonment. In 4th century BC, the ancient Greeks colonized the bay of Kuwait under Alexander the Great. The ancient Greeks named mainland Kuwait ''Larissa'' and Failaka was named ''Ikaros''. The bay of Kuwait was named ''Hieros Kolpos''. According to Strabo and Arrian, Alexander the Great named Failaka ''Ikaros'' because it resembled the Aegean island of that name in size and shape. Some elements of Greek mythology were mixed with the local cults in Failaka. "Ikaros" was also the name of a prominent city situated in Failaka. Remains of Greek colonization were also discovered in Akkaz and Umm an Namil. Large Hellenistic forts and Greek temples were uncovered.
