He traveled the world photographing people, journeying through jungles, rivers and swamps. He stayed with the Papuans, met the Kalash, the descendants of Alexander the Great in India, and was a founding member of the Association for the Orphans of Ethiopia. Yiannis Psilakis returned to Greece and prepared an exhibition of his work. «It’s time to do it and bring out the book,» he told his mother, Titi. But fate intervened and he lost his life at the age of 39, on the Athens-Lamia highway. Now, nine months later, the exhibition and the book are on display at the Benaki Museum, just as he had planned. The exhibition, titled «The World is One,» will open on Tuesday, November 21, at 8 p.m. The Benaki Museum is located at 1 Koumbari Street in Kolonaki. For information, tel 210.367.1000.
