Ilopango

Ilopango (a lake of Central America, in the republic and 6 m. S. E. of the city of San Salvador. It is about 14 m. long by 6 broad, and is clearly of volcanic origin. On all sides it is surrounded by high, abrupt hills, composed of scoriae and volcanic stones. It receives no tributary streams, although it has a small outlet, flowing through a dark narrow ravine into the Rio Jiboa, near the base of the volcano of San Vicente. The surface of the water is not less than 1,200 ft. below the level of the surrounding country. When the surface is ruffled by a breeze, it takes a brilliant green color, and exhales a disagreeable sulphurous odor.

Ilxion

Ilxion, a mythical Thessalian prince, king of the Lapithae, and father of Pirithous. When De'ioneus, whose daughter Dia he had espoused, demanded of him the customary bridal gifts, Ixion treacherously invited him to a banquet, and then had him cast into a fiery pit. None would hold intercourse with the murderer, or purify him, till Jupiter at length performed the necessary rite, and made him his guest. But Ixion presumed to make love to Juno, whereupon Jupiter made a phantom resembling her, by which Ixion became the progenitor of the centaurs. For his impiety he was chained by Mercury to a wheel which revolved perpetually in the air.

Inachus

Inachus (a mythical king, represented as the first ruler and priest of Argos, which, as well as the river Inachus, was often called after him. When Neptune and Juno contended for the possession of that country, he decided in favor of the latter, and thus incurred the anger of Neptune, who caused a dearth of water in his dominions. Several attempts have been made, even by the ancients, to explain the stories about Inachus; and it is considered probable that he was the leader of an Egyptian or Libyan colony which came across the sea and united with the Pelasgians.
