The statue of Laocoön and His Sons, also called the Laocoön Group (Italian: Gruppo del Laocoonte), has been one of the most famous ancient sculptures since it was excavated in Rome in 1506 and put on public display in the Vatican Museums, where it remains today. The statue is very likely the same one praised in the highest terms by Pliny the Elder, the main Roman writer on art, who attributed it to Greek sculptors but did not say when it was created. The figures are nearly life-sized, with the entire group measuring just over 2 m (6 ft 7 in) in height. The sculpture depicts the Trojan priest Laocoön and his sons Antiphantes and Thymbraeus being attacked by sea serpents.
The Laocoön Group has been called "the prototypical icon of human agony" in Western art. Unlike the agony often portrayed in Christian art depicting the Passion of Jesus and martyrs, the suffering here suggests neither redemption nor reward. The agony is conveyed through the contorted facial expressions, particularly Laocoön's bulging eyebrows, which were noted by Guillaume Duchenne de Boulogne as physiologically impossible. These expressions are mirrored in the struggling bodies, especially Laocoön's, with every part of his body shown straining.
