In
Greek mythology, the
Planctae ("wandering rocks") were a group of rocks, between which the sea was mercilessly violent. The
Argo (led by
Jason) was the only ship to navigate them successfully (with divine help from
Hera,
Thetis and the
Nereids). Jason chose to brave the Planctae instead of
Scylla and
Charybdis.
