“ Astyra, a town of Mysia, Mela, Pliny: Strabo calls it a hamlet, near which is a grove of Diana, thence named Astyrena: this Astyra is near Adramytrium, and to be distinguished from another near Abydos, which had a gold mine, Strabo. This last was a town of Troas; in ruins in Strabo’s time” ( MacBean 1773). Stebbing (1888: 1668) suggested that the name Astyra derives from Αστυρα or Astura, which is the name of a river in Asturia ( Spain).
