ATER
ATER or
NIGER MONS, a mountain range of Inner Libya, on the N. side of the Great Desert (
Sahara), dividing the part of Roman Africa on the Great Syrtis from Phazania (
Fezzan).
It seems to correspond either to the
Jebel-Soudan or
Black Mount(ins, between 28° and 29° N. lat., and from about 10° E. long. eastward, or to the SE. prolongation of the same chain, called the
Black Harusch, or both.
The entire range is of a black basaltic rock, whence the ancient and modern names (
Plin. Nat. 5.5,
6.30. s. 35; Hornemann,
Reisen von Kairo nach Fezzan, p. 60).
