Three male figures, nearly life-sized, carved in marble. A bearded man at the centre and two younger figures beside him are entwined with two large serpents. The central figure's face is contorted, his right arm bent sharply back, his body twisting. One of the younger figures is slumping, the other still struggling.

III · THE WORK · ART HISTORY

Laocoön and His Sons

Hellenistic sculpture · 1st century BC (disputed) · Marble

Dug up in Rome in 1506, restored immediately with the wrong arm, and not corrected until 1906 — when the original turned up in a builder's yard.
