Idoj de Orfeo (English: Children of Orpheus) is a novel written in Esperanto by Hendrik Bulthuis.

Once, a man named Johano swam to the island nude, since his ship had sailed off while he was bathing.

The parents dressed him and hosted him for a month, during which time he told the boy fables and described continental cities.

In port in Russia, the cook, Ivan, took him to see the city, but got drunk and was arrested, leaving the boy to sleep for several days in a cemetery, where he was found by other parents burying their own dead son.

In the village Brey, Rika returns home one day to find a baby boy in a box on the table; she calls him Moses.

Johano, the man who had visited the family on the island, encounters Ivan, the ship's cook who had been arrested.

There they said goodbye to Johano, who it turned out, was not human at all, but a supernatural being, who had come to protect the three boys, children of Orpheus.
