in
sailor's mythology, Davy
Jones is the name
given to the
devil who lives at the bottom of the
sea. He is
thought by some to have been a Welshman who became the devilish
guardian of the deep who regards the bottom of the ocean as his storeroom. Hence anyone who falls overboard and drowns is said to have gone to Davy
Jones' locker.
