  The Dacians were known as Geta (plural Getae) in Ancient Greek writings, and as Dacus (plural Daci) or Getae in Roman documents, but also as Dagae and Gaete as depicted on the late Roman map Tabula Peutingeriana. It was Herodotus who first used the ethnonym Getae in his Histories. In Greek and Latin, in the writings of Julius Caesar, Strabo, and Pliny the Elder, the people became known as 'the Dacians'. Getae and Dacians were interchangeable terms, or used with some confusion by the Greeks. Latin poets often used the name Getae. Vergil called them Getae four times, and Daci once, Lucian Getae three times and Daci twice, Horace named them Getae twice and Daci five times, while Juvenal one time Getae and two times Daci. In AD 113, Hadrian used the poetic term Getae for the Dacians. Modern historians prefer to use the name Geto-Dacians. Strabo describes the Getae and Dacians as distinct but cognate tribes. This distinction refers to the regions they occupied. Strabo and Pliny the Elder also state that Getae and Dacians spoke the same language.
  
  By contrast, the name of Dacians, whatever the origin of the name, was used by the more western tribes who adjoined the Pannonians and therefore first became known to the Romans. According to Strabo's Geographica, the original name of the Dacians was Δάοι " Daoi ". The name Daoi (one of the ancient Geto-Dacian tribes) was certainly adopted by foreign observers to designate all the inhabitants of the countries north of Danube that had not yet been conquered by Greece or Rome.
  
  The ethnographic name Daci is found under various forms within ancient sources. Greeks used the forms Δάκοι " Dakoi " (Strabo, Dio Cassius, and Dioscorides) and Δάοι "Daoi" (singular Daos). The form Δάοι "Daoi" was frequently used according to Stephan of Byzantium.
  
  Latins used the forms Davus, Dacus, and a derived form Dacisci (Vopiscus and inscriptions).
  
  There are similarities between the ethnonyms of the Dacians and those of Dahae (Greek Δάσαι Δάοι, Δάαι, Δαι, Δάσαι Dáoi, Dáai, Dai, Dasai; Latin Dahae, Daci), an Indo-European people located east of the Caspian Sea, until the 1st millennium BC. Scholars have suggested that there were links between the two peoples since ancient times. The historian David Gordon White has, moreover, stated that the "Dacians... appear to be related to the Dahae". (Likewise White and other scholars also believe that the names Dacii and Dahae may also have a shared etymology – see the section following for further details.)
  
  By the end of the first century AD, all the inhabitants of the lands which now form Romania were known to the Romans as Daci, with the exception of some Celtic and Germanic tribes who infiltrated from the west, and Sarmatian and related people from the east.
