Athenodoros, Hagesandros, and Polydoros
"the prototypical icon of human agony" in Western art.
Laocoön and His Sons / Laocoön Group, most likely dating to the 1st c. B.C. or1st c. C.E., made of six blocks of Greek Parian marble max H: 2 m (6 ft 7 in). Today in the Octagonal Court / Cortile delle Statue, Vatican.
The "wrong" and full version of it from a 1795 "Royal Academicians in General Assembly" painting by Henry Singleton
Excavated damaged in 1506 and has undergone speculative interventions to show the whole work (all missing parts creatively restored). Since 1980s the group is rid of Jacopo Sansovino's (1st) and Michelangelo's apprentice Giovanni Antonio Montorsoli's extencive restorations, after Ludwig Pollak discovered a missing part of the much debated Right arm, in 1906 (which confirmed Michelangelo's rejected initial view).
Pliny attributed the work (still in Emperor Titus' palace then) to three Greek sculptors from the island of Rhodes: Agesander, Athenodoros, and Polydorus, but he did not mention date or patron. An enigmatic Hellenistic "baroque" masterpiece [a unique surviving instant of huge visual impact, without any intermediate, possibly offensive restoration. It seems almost Doric in comparison with Gian Lorenzo Bernini's baroque view]
Paradox: Laocoon seems convinced by Cassandra's already delivered but never-to-be-believed Trojan Horse accurate prophecy [?]
