NAISSUS
NAISSUS (
Ναϊσσός,
Steph. B. sub voce Νᾶσσος,
Ptol. 3.9.6;
Νάϊσος, Zosim. 3.11;
Ναῖσός, Hierocl. p. 654), an important town in Upper Moesia, situated in the district Dardania, upon an eastern tributary of the river Margus, and upon the military road running through this country.
It was in the neighbourhood of Naissus that Claudius II. gained
[p. 2.396]his victory over the Goths in A.D. 269 (Zosim. 1.45); but the town is chiefly memorable as the birthplace of Constantine the Great. (
Steph. B. sub voce Const. Porph.
de Them. 2.9. p. 56, ed. Bonn.)
It was destroyed by the Huns under Attila (Priscus, p. 171, ed. Bonn.), but was restored by Justinian (Procop. 4.1, where it is called Naisopolis).
It still exists under the name of
Nissa, upon the river
Nissava, an affluent of the
Morava.
