Ida #1

I. A mountain range (now Kas Dagh) of Mysia, forming the S. boundary of the Troad. Its highest peak was Mt. Gargarus, about 5,750 ft. above the sea. The principal rivers flowing from Mt. Ida were the Simois, Sca-mander, and Granicus. From Mt. Ida Ganymede was stolen; here Paris pronounced judgment on the beauty of the rival goddesses; and here the celestials stationed themselves to behold the battles for Troy on the plain below. II. A mountain (now Psiloriti) of Crete, the loftiest of the range which traverses that island, of which it occupies the centre, terminating in three peaks crowned with snow for eight months of the year. Its highest summit is said to be about 8,000 ft. Of the legends with which its name is connected, those relating to the infancy of Zeus are the most celebrated.
