Described by Livy as one of the Capitae Etruriae (Etruscan capitals), Arezzo is believed to have been one of the twelve most important Etruscan cities—the so-called Dodecapolis. Etruscan remains establish that the acropolis of San Cornelio, a small hill next to that of San Donatus, was occupied and fortified in the Etruscan period. There is other significant Etruscan evidence: parts of walls, an Etruscan necropolis on Poggio del Sole (still named "Hill of the Sun"), and most famously, the two bronzes, the "Chimera of Arezzo" (5th century BC) and the "Minerva" (4th century BC) which were discovered in the 16th century and taken to Florence. Increasing trade connections with Greece also brought some elite goods to the Etruscan nobles of Arezzo: the krater painted by Euphronios ca 510 BC with a battle against Amazons (in the Museo Civico, Arezzo 1465) is unsurpassed.

Conquered by the Romans in 311 BC, Arretium became a military station on the via Cassia, the road to expansion by republican Rome into the basin of the Po. Arretium sided with Marius in the Roman Civil War, and the victorious Sulla planted a colony of his veterans in the half-demolished city, as Arretium Fidens ("Faithful Arretium"). The old Etruscan aristocracy was not extinguished: Gaius Cilnius Maecenas, whose name is eponymous with "patron of the arts", was of the noble Aretine Etruscan stock. The city continued to flourish as Arretium Vetus ("Old Arretium"), the third largest city in Italy in the Augustan period, well known in particular for its widely-exported pottery manufactures, the characteristic moulded and glazed Arretine ware, bucchero-ware of dark clay and red-painted vases (the so-called "coral" vases).
