The Bastarnae, Bastarni or Basternae, also known as the Peuci or Peucini, were an ancient people who are known from Greek and Roman records to have inhabited areas north and east of the Carpathian Mountains between about 300 BC and about 300 AD, stretching in an arc from the sources of the Vistula in present-day Poland and Slovakia, to the Lower Danube, and including all or most of present-day Moldava. The Peucini were sometimes described as a subtribe, who settled the Peuke Island in the Danube Delta, but apparently due to their importance their name was sometimes used for the Bastarnae as a whole. Near the sources of the Vistula another part of the Bastarnae were the Sidones, while the Atmoni, another tribe of the Bastarnae are only mentioned in one listing by Strabo.
