Cotiso

Cotiso, Cotish or Cotison (flourished c. 30 BC) was a Dacian or Getic king who apparently ruled the mountains between Banat and Oltenia (modern-day Romania). Horace and Florus call him a Dacian; Suetonius calls him king of the Getae. Florus wrote in his account of Roman history that Cotiso and his armies used to attack towards south when the Danube froze.
