The Orpheus Monument (Slovene: Orfejev spomenik) is a Roman monument in Ptuj, Slovenia, an almost 5 metres (16 ft) high and about 1.8 metres (5 ft 11 in) wide stele, carved of white Pohorje marble.
[3] The monolith was originally a grave marker, erected in the 2nd century AD to honor the memory of Marcus Valerius Verus, the duumvir (mayor) of Roman Poetovio.
[3] The central relief illustrates scenes from the myth of Orpheus, who plays the lyre while mourning his lost love Eurydice.
Other reliefs depict the Greek-Egyptian god Serapis, who symbolizes the hope of resurrection.
Beneath this, a relief in the tympanum depicts the Moon goddess Selene, leaning over her dead lover Endymion.
