Geomorphological and paleo-environmental studies have shown that the Phoenician colony of Cerro del Villar, at the mouth of the Guadalhorce, was situated on an ancient island, now a rise in an alluvial flood plain west of Málaga.
[7] The Periplus, a merchants' guidebook which described the sea routes used by traders from Phoenicia and Tartessos, possibly dating to as early as the 6th century BC, contains the most ancient identification of Malaca as Mainake.
The part referring to the Iberian Peninsula is preserved in the Ora Maritima (The Maritime Shores) of the Latin writer Rufus Festus Avienius, who wrote down excerpts much later, during the 4th century.
[9] According to the ancient sources it was gradually abandoned after the battle of Alalia and the consequent collapse of the Phocaean Greek trade, which led the native inhabitants to shift their residence to the Phoenician-Punic Malaka.
[11][12]The layout of ancient Malaka is unknown, but its location on a hill at the foot of Mount Gibralfaro suggests it was a more dense and irregular urban cluster than neighbouring Cerro del Villar, that is, Mainake.
The ruins mentioned by Strabo were still visible in the 1st century BC, and could only belong to a place that was already vacated in the Roman period, as occurred in Cerro del Villar but not in Malaka.
The Phoenician city at Cerro del Villar lay in ruins at the beginning of the 6th century BC, when it was apparently resettled by the Phocaean Greeks.
