ACHAEA. Patrae; Septimius Severus

The first traces of settlement in Patras date to as early as the third millennium BC, in the area of modern Aroe. Patras flourished for the first time in the Post-Helladic or Mycenean period (1580–11). Ancient Patras was formed by the unification of three Mycenaean villages in modern Aroe; namely Antheia (from mythological Antheia) and Mesatis. Mythology has it that after the Dorian invasion, a group of Achaeans from Laconia led by the eponymous Patreus established a colony. In antiquity Patras remained a farming city. It was in Roman times that it became an important port.

After 280 BC and prior to the Roman occupation of Greece, Patras played a significant role in the foundation of the second "Achaean League" (Achaiki Sympoliteia), along with the cities of Dyme, Tritaeaand Pharai. Later on, and following the Roman occupation of Greece in 146 BC, Patras played a key role, and Augustus refounded the city as a Roman colony in the area. In addition, Patras has been a Christian center since the early days of Christianity, and it is the city where Saint Andrew was crucified.
