Trihemiobol - Orou

Orou was a dynast operating in the Carian interior during the period of loosening Achaemenid administrative control that followed the Peloponnesian War. His issues are poorly documented in ancient literary sources, making the coins themselves the primary evidence for his existence and authority. The reference spread here — Müseler, Rosen, SNG von Aulock — reflects decades of die-study work trying to establish a coherent sequence for the minor Carian dynasts, none of whom struck in large volume.

The trihemiobol denomination places this squarely in local fractional commerce rather than inter-regional trade.
