In Greek mythology, two sacred mountains are called Mount Ida, the "Mountain of the Goddess": Mount Ida in Crete; and Mount Ida in the ancient Troad region of western Anatolia (in modern-day Turkey) which was also known as the Phrygian Ida in classical antiquity and is the mountain that is mentioned in the Iliad of Homer and the Aeneid of Virgil. Both are associated with the mother goddess in the deepest layers of pre-Greek myth, in that Mount Ida in Anatolia was sacred to Cybele, who is sometimes called Mater Idaea ("Idaean Mother"), while  Rhea, often identified with Cybele, put the infant Zeus to nurse with Amaltheia at Mount Ida in Crete. Thereafter, his birthplace was sacred to Zeus, the king and father of Greek gods and goddesses.
