The Tetrarchs
description: This porphyry statue depicting the four Tetrarchs (Diocletian, Maximian, Galerius, and Constantius I), was originally designed as two separate sculptures that should show an Augustus and a Caesar. It most likely originally decorated the Philadelphion in Constantinople and arrived in Venice soon after the sack of Constantinople in 1204.
