594 THE NATIONAL GEOGRAPHIC MAGAZINE Photograph from Alexander Wilbourne Weddell THE MONUMENT OF THRASYLLOS The grotto seen in the foreground is mentioned by Pausanias; it is now a Greek chapel. The monument was destroyed by the Turks when they fired their artillery against the Acropolis in 1827. The two columns above the grotto supported votive tripods, the holes in which they were inserted being still visible at the top. The walls are those built by Cimon, son of the great Miltiades, the victor at Marathon.
