The seer Laocoon warned the Trojans against the Wooden Horse (as Cassandra also did), telling them not bring that piece of art into the city.

And because he threw his spear against it, a deity sent from neighboring islands, snakes to kill his sons; and while trying to help them, he was blinded or even killed.

Fateful device

Troy was taken in the tenth year of the war, not mainly by force but through the stratagem of the Wooden Horse, conceived by Odysseus: The Achaeans let the architect Epeius fall timber on Mount Ida and construct a Wooden Horse with a hollow interior and an opening in the side.

Then, following Odysseus' advice, they introduced the best warriors into that dangerous device, and after appointing Odysseus their leader, they engraved on the horse a treacherous inscription:

"For their return home, the Achaeans dedicate this thank-offering to Athena." (Apollodorus, Library "Epitome" 5.15).

This is how the Achaeans feigned retreat; and the next day the Trojans, finding the enemy camp deserted and believing that the Achaeans had fled, dragged the horse to the citadel.

Cassandra's warning

Having stationed it beside the king's palace, they deliberated what they should do, whether to hurl it down from the rocks, to burn it, or to let it stand as a great offering to the gods.

It was then that the god-maddened seeress Cassandra declared, with her frenzied voice, that there was an armed force hidden inside the Wooden Horse, warning the others thus:

"O wretched men! why rage you possessed, dragging this unfriendly horse, hasting to your last night and the end of the war and the sleep that knows no waking?" (Cassandra to the Trojans. Tryphiodorus, The Taking of Ilios 375).

Yet no one was to believe Cassandra; for she had been cursed by the same god who gave her the gift of prophecy in exchange for a promise she never fulfilled.

So Apollo (for this one was the god), avenging the broken promise, caused her prophecies not to be believed.

Laocoon's short appearance

It is now that the seer Laocoon, priest of Apollo, comes into the story for the first time (for nothing is told about his childhood or youth), confirming Cassandra and exhorting the Trojans to burn the Wooden Horse:

"Is it thus you know Odysseus? Trojans, trust not the horse. Whatever it be, I fear the Greeks, even when bringing gifts." (Laocoon to the Trojans. Virgil, Aeneid 2.48).

Some say that Laocoon even threw his spear against the horse.

Athena stays Laocoon

But others say that the Trojans were about to obey him when Athena shook the foundations of the earth at his feet as a warning; and since he did not cease to exhort the Trojans, the goddess, stabbing his eyeballs with anguish, robbed him of his sight.

And when he nevertheless persisted, she sent two serpents or dragons from Calydna against the sons of the seer, chaining their feet as all others, except their father, escaped. This is how, some say, Laocoon's sons died, and their father was blinded.

Apollo sent the snakes

Yet others affirm that it was Apollo who sent the two serpents swimming through the sea from the neighboring islands to devour the sons of Laocoon, and that as he hurried, weapon in hand, to help his sons, he was killed by the monsters, which, gliding away, disappeared into a shrine.

The force of adversity

Now, if the snakes had not come, or if Laocoon had succeeded in defeating them, he had been deemed to be a very wise man, who knew the secret of the Wooden Horse without opening it.

But since adverse circumstances overwhelmed him, many argued that the man had got what he deserved, and that the horse should be brought to the shrine of Athena (the same goddess who was misleading them), which they did, thus laying open the heart of the city.

For the majority among the Trojans, being no different from any other majority of men, preferred success before good sense, and seeing how Laocoon had been destroyed, they refused to imagine that a man, though defeated, could still be in possession of the truth.

But the majority must prevail, sometimes against all sense; and so, since most Trojans were in favor of sparing the wonderful horse, they all ended, as a result, sleeping with the enemy within the walls. The majority never woke up, being slain in their beds.

Additional note

Now, why would Apollo sent the monsters to destroy his priest? According to Frazer, Servius (himself based on Euphorion) says that Laocoon had incurred the wrath of the god by sleeping with his wife in the presence of the deity's image; and Frazer adds that Tzetzes affirms that Laocoon's son died in the temple of the Thymbraean Apollo, the scene of the sacrilege thus becoming the scene of the punishment. Concerning the famous statue (see copy at top of page). says Frazer:

"That group, the work of three Rhodian sculptors, graced the palace of the emperor Titus in the time of Pliny, who declared that it was to be preferred to any other work either of sculpture or painting." (Pliny, Nat. Hist. xxxvi.37).

Laocoon is the same as Lacoon, one of the Argonauts.
