Narrative
Homer opens Book 12 with a prolepsis: when Troy has fallen and the best Achaeans are dead or scattered, Poseidon and Apollo will turn the rivers of the Troad against the Achaean wall, wash nine days, and bury the fortifications under sand so that no trace remains—Poseidon’s answer to a wall built without sacrifice and rival to his own Trojan masonry. The poet thus explains why travelers in his day see no Achaean rampart by the Hellespont.
Catalogue this as the gods’ destruction of the Achaean wall—narrative future embedded in the *Iliad*—distinct from the building and the teichomachy.
