The den of Cacus was properly Ca-Chus, the cavern or temple of Chus, out of which the poets, and later historians have formed a strange personage, whom they represent as a shepherd, and the son of Vulcan. Many antient Divinities, whose rites and history had any relation to Ur in Chaldea, are said to have been the children of Vulcan; and oftentimes to have been born in fire. There certainly stood a temple of old upon the Aventine mountain in Latium, which was the terror of the neighbourhood. The cruelties of the priests, and their continual depredations, may be inferred from the history of Cacus. Virgil makes Evander describe the place to Æneas; though it is supposed in his time to have been in ruins. [680]Jam primum saxis suspensam hanc aspice rupem, Disjectæ procul ut moles, desertaque montis Stat domus, et scopuli ingentem traxere ruinam. Hic spelunca fuit, vasto submota recessu, Semihominis Caci, facies quam dira tegebat, Solis inaccessum radiis: semperque recenti Cæde tepebat humus; foribusque affixa superbis Ora virûm tristi pendebant pallida tabo. Huic monstro Vulcanus erat pater. Livy mentions Cacus as a shepherd, and a person of great strength, and violence. [681]Pastor, accola ejus loci, Cacus, ferox viribus. He is mentioned also by Plutarch, who styles him Caccus, Κακκος. [682]Τον μεν γαρ Ἡφαιστου παιδα Ρωμαιοι Κακκον ἱστορουσι πυρ και φλογας αφιεναι δια του στοματος εξω ῥεουσας. As there were both priests, and priestesses, in temples of this sort, persons styled both Lami, and Lamiæ; so we read both of a Cacus, and a Caca. The latter was supposed to have been a Goddess, who was made a Deity for having betrayed her brother to Hercules. [683]Colitur et Caca, quæ Herculi fecit indicium boum; divinitatem consecuta, quia perdidit fratrem. In short, under the characters of Caca, and Cacus, we have a history of Cacusian priests, who seem to have been a set of people devoted to rapine and murder. What we express Cocytus, and suppose to have been merely a river, was originally a temple in Egypt called Co-Cutus: for rivers were generally denominated from some town, or temple, near which they ran. Co-Cutus means the Cuthite temple, the house of Cuth. It was certainly a place of inquisition, where great cruelties were exercised. Hence the river, which was denominated from it, was esteemed a river of hell; and was supposed to have continual cries, and lamentations resounding upon its waters. [684]Cocytus, named of lamentation loud Heard on its banks.
