Danastus

Another name of the Tyras or Dniester. It is called Danastus by Ammianus Marcellinus (xxxi. 3), and Danastris by Constantine Porphyrogenitus. It rises from a lake amid the Carpathian Mountains in Galicia, and empties into the Black Sea after a course of about six hundred miles. The name Tyras (Τύρας) occurs in Ptolemy, Strabo, Stephanus of Byzantium, and Scymnus of Chios. Herodotus gives the Ionic form Τύρης (Herod.iv. 51).
