(anc. geog.), a country which Trajan, who reduced it to a province, joined to Moesia by an admirable bridge. This country lies extended between the Danube and the Carpathian mountains, from the river Tibiscus, quite to the north bend of the Danube; so as to extend thence in a direct line to the mouth of the Danube and to the Euxine; on the north-side next the Carpathes, terminated by the river Hierasus, now the Pruth; on the west by the Tibiscus or Teiss; comprising a part of Upper Hungary, all Transylvania and Walachia, and a part of Moldavia. Daci, the people; a name which Strabo takes to be the same with the Davi of Comedies: neighbours, on the west, to the Getæ; an appellation common also in Comedies. Josephus mentions a set of religious men among the Daci, whom he calls Plisti, and compares with the Esseni; of these Plisti no other author makes any mention. Dacicus, the epithet; assumed by some emperors, (Juvenal.) There was a Dacia Aureliana, a part of Illyricum, which was divided into the eastern and western; Sirmium being the capital of the latter, and Sardica of the former. But this belongs to the lower age.
