The Arch of Hadrian, Athens (Verso)

In this depiction of the ancient city's remains, Philippos Margaritis, a native-born Greek, and Philibert Perraud, a Frenchman, photographed the Arch of Hadrian at Athens, a masterpiece of classical architecture. The Arch, built around 131 A.D., is a light, elegant structure, with an opening flanked by freestanding columns and a colonnaded upper story. Barely visible beyond the Arch at upper right is the distant mount of the Acropolis.
