When earth-encircling Neptune heard this, he went to Scheria where the Phaeacians live, and stayed there till the ship, which was making rapid way, had got close in. Then he went up to it, turned it into stone, and drove it down with the flat of his hand so as to root it in the ground.
~ The Odyssey - Book XIII (Samuel Butler Translation. p256)
One of the most dramatic scenes in book 13 is when the Phaecian ship, which was returning after dropping off Ulysses to Ithaca, suddenly turns to stone and sinks to the bottom of the sea, just as it is pulling into the harbor in the full view of people of Phaecia.
Ulysses comes to this island at the end of book 5. From Book 6 to Book 13, King Alcinous, his daughter, and people in the court - everyone is extraordinarily generous and helpful. They give gifts to Ulysses selflessly, and there is also a mention in a couple of places about the fame of Phaecians as the best hosts and people who are always kind to strangers who come to their island. But when they send their best men with Ulysses to Ithaca with a ship full of gifts and come back to their homeland, their ship gets destroyed before it reaches the shore. In their shock, they decide to never again help a stranger who comes to their island.
