To communicate from mountaintop to mountaintop, the ancestors developed a language that resembled the sounds of birds. With it they could articulate any syllable and every word, and exchange messages across large distances. Panagiotis Tzanavaris, Jiannis Apostolou, Kostas Giannakaris, and Panagiotis Bournousouzis learned the ancient language of the mountains along with their native tongue. Through their remarkable skill, on location at Mount Olympus, the timeless verses selected by Kostas Ioannidis are transformed into birdsong, and the poets’ words become one with the mystical natural environment. Memory of, memory of, memory of is a sound installation specially commissioned by the Onassis Foundation (USA) in conjunction with the exhibition Gods and Mortals at Olympus: Ancient Dion, City of Zeus.
