Zirkoff, Boris

Sostratus. Son of Dexiphanes, of Cnidus, one of the great architects who flourished during and after the life of Alexander the Great. He built for Ptolemy I, the son of Lagus, at the expense of 800 talents, the famous Pharos of Alexandria. He also embellished his native Cnidus with a work that was one of the wonders of ancient architecture — a portico or collonade, supporting a terrace, which served as a promenade and is referred to by Pliny as pensilis ambulatio. (Vide Pliny, Hist. Nat., XXXVI, 12; Strabo, XVII, p. 791; Suidas, s.v. Pharos.)
