Aria (Ἀρ(ε)ία Ar(e)ía, آريا; Latin Aria, representing Old Persian. 𐏃𐎼𐎡𐎺 Haraiva, Avestan 𐬵𐬀𐬭𐬋𐬌𐬬𐬀 Harōiva) was an Achaemenid region centered on the city of Herat in present-day western Afghanistan. In classical sources, Aria has been several times confused with the greater region of ancient Ariana, of which Aria formed a part. Aria was an Old Persian satrapy, which enclosed chiefly the valley of the Hari River (Greek Ἄρ(ε)ιος, this being eponymous to the whole land according to Arrian) and which in antiquity was considered as particularly fertile and, above all, rich in wine. The region of Aria was separated by mountain ranges from the Paropamisadae in the east, Parthia in the west and Margiana and Hyrcania in the north, while a desert separated it from Carmania and Drangiana in the south. It is described in a very detailed manner by Ptolemy and Strabo and corresponds, according to that, almost to the Herat Province of today's Afghanistan. In this sense the term is used correctly by some writers, e.g. Herodotus (3.93.3, where the Areioi are mentioned together with the Parthians, Chorasmians, and Sogdians); Diodorus (17.105.7; 18.39.6); Strabo (2.1.14; 11.10.1, cf. also 11.8.1 and 8; 15.2.8 and 9); Arrian (Anabasis 3.25.1); Pomponius Mela (1.12, where we read that “nearest to India is Ariane, then Aria”). Its original capital was Artacoana (Ἀρτακόανα) or Articaudna (Ἀρτίκαυδνα) according to Ptolemy. In its vicinity, a new capital was built, either by Alexander the Great himself or by his successors, Alexandria Ariana (Ἀλεξάνδρεια ἡ ἐν Ἀρίοις), modern Herat in northwest Afghanistan. Ptolemy lists several other cities, an indication of the province's wealth and fertility. The most important, according to Ptolemy and Arrian were: The Persian Achaemenid district of Aria is mentioned in the provincial lists that are included in various royal inscriptions, for instance, in the Behistun inscription of Darius I (c. 520 BC). Representatives from the district are depicted in reliefs, e.g., at the royal Achaemenid tombs of Naqsh-e Rustam and Persepolis.
