During his lifetime he built a re markable monument to himself on the summit of Nemrud Dagh, a 7,500-foot mountain in what is now southeastern Turkey (see page 38). The monument consists of a huge mound of loose stones surrounded by three terraces decorated with re liefs, altars and colossal statues of Antiochus and his curious hybrid gods. In the photograph on the cover the slope of the mound may be seen at the upper left. The head of Amplifier Antiochus stands amid the rubble combinations in 1500, 5,000 and of fallen statuary on the West Ter 15,000 pound force ratings race of the monument.
