Another 20th century poet fascinated with Orpheus was, of course, Rainer Maria Rilke. Jutta sends along this poem, translated by Tony Kline, our online translator of Ovid and much else.
Here's the beginning of Orpheus. Eurydice. Hermes:

As secret ores of silver they passed

For comparison, here's the same poem translated by Stephen Mitchell.
Rilke also wrote 55 Sonnets to Orpheus, found here in a translation by Howard A. Landman.
