Ulysses and the Sirens by J. W. Waterhouse

A siren is a creature in Greek mythology. The sirens were living on an island surrounded by rocks. Sirens also have a mermaid form where they still sing, but they hit the boat to sink it that way and sirens have a human form. Sailors would try to go to them because of their singing, and their ships would get destroyed on the rocks, and they would drown.
