The Wandering Rocks encountered by Odysseus, blazing cliffs through which only the Argo ever passed,‌​‌​‍​‍​‌​‍​‍​‍​‍​‍​‍​‌​‍​‌​‌​‌​‌​‍​‌​‌​‍​‌​‍​‍​‌​‌​‌​‌​‌​‍​‌​‍ offered as an alternative route to Scylla and Charybdis.

The Story of Clashing Rocks

The Planctae, or Wandering Rocks, were described by Circe as an alternative to the strait of Scylla and Charybdis.‌​‌​‍​‍​‌​‍​‍​‍​‍​‍​‍​‌​‍​‌​‌​‌​‌​‍​‌​‌​‍​‌​‍​‍​‌​‌​‌​‌​‌​‍​‌​‍ Unlike the Symplegades that the Argonauts passed, the Planctae were surrounded by fire and crashing waves, and no ship had ever survived them except the Argo, which Hera guided safely through out of love for Jason. Even doves carrying ambrosia to Zeus lost one of their number to the rocks each flight, and Zeus always had to replace the lost bird. Circe advised Odysseus to avoid the Planctae entirely and instead choose the strait where Scylla and Charybdis waited. Scylla would take six men — one for each of her six heads — but the ship would survive. The Planctae would destroy them all. This forced choice between certain partial loss (Scylla) and probable total destruction (Planctae) gave Odysseus one of his most agonising leadership decisions: to sacrifice some crew members knowingly to save the rest.

Fun Fact

The "Scylla or Charybdis" dilemma — choosing between two terrible options — became one of the most used idioms in English and European languages, but Homer actually presented three options: Scylla, Charybdis, or the Planctae. The third option (total destruction) was rejected so quickly that it disappeared from the idiom. Leadership theory calls this "the Odysseus problem" — the hardest decisions aren't between good and bad, but between bad and worse, with the truly catastrophic option already eliminated.
