Artacoana^[1][2] (Ancient Greek: Ἀρτακόανα) or Artacana^[3] or Articaudna^[4] (Ἀρτίκαυδνα) or Chortacana^[5] or Artacaena,^[6] name of the capital of Aria, an eastern satrapy of the Persian empire.

In the early nineteenth century a Persian Achaemenid cuneiform cylinder seal was found in or near Herat.^[10]
