Significantly there is a story about Heracles, Hylas and Polyphemus, where Hylas is 'killed' at a well. Enough to listen attentively.

Heracles is the strong man, strong as an oak, 'Heracles of Tiryns, the strongest man who ever lived, now a god'.

Hylas is the close friend of Heracles, 'Hylas the Dryopian, squire to Heracles'.

At first there is a test of strength among the 50 rowers, of course at the initiative of Heracles, who of course also wins. But then his oar breaks.
