of the Aous. When describing the Illyrian invasion of Macedonia ruled by Argaeus I, somewhere between 678–640 BC, the historian Polyaenus ( 2nd-century AD) recorded the supposed oldest known king in Illyria, Galaurus or Galabrus, a ruler of the Taulantii who reigned in the latter part of the 7th century BC. Some scholars consider the authenticity of Polyaenus' passage as disputable. Whether or not this account is historically reliable, and despite Polyaenus' interest in the anecdote, it implies the widespread thought throughout antiquity about a significant animosity between the Macedonians and the Illyrians as early as the 7th century BC, if the consensus in modern scholarship in dating the reigning period of Argaeus I is correct. Friendly relationships were created between Corinthians and certain Illyrian tribes. In the 7th century BC the Taulantii invoked the aid of Corinth and Corcyra in a war against the Liburni. After the defeat and expulsion of the Liburni from the region, the Corcyreans founded in 627 BC on the Illyrian mainland a colony, mixing with the local population and establishing the Greek element to the port. The city was called Epidamnos-Dyrrhachion, thought to have been the names of two barbarian/Illyrian rulers of the region. The double name was determined by the presence of a pre-existing Illyrian settlement presumably located on the hills (Epidamnos), while the plain, formerly occupied by a lagoon communicating with the sea, provided favorable conditions that created a natural harbor (Dyrrachion). The Greek colony was therefore founded in a territory that corresponded to a narrow promontory surrounded by the sea that gave the city the appearance of an island. A flourishing commercial centre emerged and the city grew rapidly. It thrived for about two centuries, mainly as a result of trade with the neighboring Illyrians of the hinterland, which was mediated by a magistrate, called ('seller'). The was chosen each year from among the citizens who were deemed worthy by the Epidamnians. Justin (2nd century AD) reports that at a time when the ruler of Macedonia was the infant Aeropus I (around 6th century BC), the Illyrians attacked successfully Macedonia until the infant ruler was brought to a battle by his Macedonian subjects, benefitting from his presence and avenging their initial defeat against the Illyrians. The name of the specific Illyrian tribe or group of tribes that attacked Macedonia is not reported in Justin's account, but it has been suggested that
