Orpheus and Eurydice, by Sybil Gräfin Schönfeldt, illustrated by Iassen Ghiuselev
Daedalus Books currently has it for $3.98 US. They actually have several children’s books of Hellenic interest, including “Run With Me, Nike” from the Smithsonian Odyssey series; as well as “Simeon’s Gift”, by Julie Andrews, which looks like it has serious potential for the Druidically inclined.
ADDENDUM, 5/8/07 – Both the other books mentioned above are indeed worthwhile. “Run With Me, Nike” is a cute little time travel story about a boy who is transported back to the ancient Olympics and prays to Nike for victory in a footrace; “Simeon’s Gift” is a lovely fable about a musician who loses his gift of music until he learns to hear the music of Nature and the world around him (basically learning to sense the flow of Awen, albeit expressed in very faintly Christian terms).
