by Ralph Pederson, a member of the institute of Nautical Archaeology and now teaching in Marburg, Germany, dismissed the claims that the trenches were a port, on various criteria. The exact function of site BEY194 may never be known, and the issue raised heated emotions and led to increased coverage on the subject of Lebanese heritage in the press. Hellenistic period In 140BC, the Phoenician city was destroyed by Diodotus Tryphon during his conflict with Antiochus VII Sidetes for the throne of the Hellenistic Seleucid monarchy. Laodicea in Phoenicia was built upon the same site on a more conventional Hellenistic plan. Present-day Beirut overlies this ancient one, and little archaeology was carried out until after the civil war in 1991. The salvage excavations after 1993 have yielded new insights into the layout and history of this period of Beirut's history. Public architecture included several areas and buildings. Mid-1st-century coins from Berytus bear the head of Tyche, goddess of fortune; on the reverse, the city's symbol appears: a dolphin entwines an anchor. This symbol was later taken up by the early printer Aldus Manutius in 15th century Venice. After a state of civil war and decline the Seleucid Empire faced, King Tigranes the Great of the Kingdom of Armenia conquered Beirut and placed it under effective Armenian control. However, after the Battle of Tigranocerta, Armenia forever lost their holdings in Syria and Beirut was conquered by Roman general Pompey. Roman period Laodicea was conquered by Pompey in 64 BC and the name Berytus was restored to it. The city was assimilated into the Roman Empire, soldiers were sent there, and large building projects were undertaken. From the 1st century BC, the Bekaa Valley served as a source of grain for the Roman provinces of the Levant and even for Rome itself. Under Claudius, Berytus expanded to reach the Bekaa Valley and include Heliopolis (Baalbek). The city was settled by Roman colonists who promoted agriculture in the region. As a result of this settlement, the city quickly became Romanized, and the city became the only mainly Latin-speaking area in the Syria-Phoenicia province. In 14BC, during the reign of Herod the Great, Berytus became a colony, one of four in the Syria-Phoenicia region and the only one with full Italian rights () exempting its citizens from imperial taxation. Beirut was considered the most Roman city in the eastern provinces of the Roman Empire.
