"Oh no – my father’s prophecy years ago…
it all comes home to me with a vengeance now!
He used to say Poseidon was vexed with us because
we escorted all mankind and never came to grief.
He said that one day, as a well-built ship of ours
sailed home on the misty sea from such a convoy,
the god would crush it, yes,
and pile a huge mountain round about our port."
– Homer
The Odyssey, Book 13, lines 194-201. The Phaeacians’ ship has been turned to stone by Poseidon and is rooted to the ocean floor. Alcinous interprets this as fulfilment of a prophecy made by his father years ago. In other words, it was fated.
