Cerainian Mountains (Gr. the thunder-riven mountains), a name given by the ancient Greeks to two different ranges.
I. One belonging to the eastern extremity of the great range of Caucasus, the precise position of which is not certainly known. Strabo makes it the name of that portion of the Caucasus which overhangs the Caspian sea, and in which he places the land of the Amazons. Mela seems to apply the name to the whole chain of the Caucasus, and Pliny gives a similarly extensive signification to it. The name in fact appears to have been used at first in conjunction with Caucasus for the highest summit of the range, and afterward applied confusedly to the eastern portion of the mountains, which were very imperfectly known to the ancients.
II. Lofty and rugged mountains in the N. part of Epirus, said to have derived their name from the thunder storms which were very frequent among them. They are often called Acroceraunian from the name of their terminal promontory, which runs out into the Ionian sea, and is now called Glossa, or by the Italians Lin-guetta. The Ceraunian mountains extended several miles along the coast from the Acro-ceraunian promontory, and were much dreaded by sailors from the storms they produced. Inland they were connected by an eastern branch with the mountains on the northern frontier of Thessaly. The inhabitants of the mountains were called Ceraunii. These mountains were famous in ancient poetry, and among the modern poets Shelley has celebrated them. Their present name is Khimara.
