Orpheus, in the Greek mythology son of Apollo and the Muse Calliopë, famed for his skill on the lyre, from which the strains were such as not only calmed and swayed the rude soul of nature, but persuaded even the inexorable Pluto to relent; for one day when his wife Eurydice was taken away from him, he descended with his lyre to the lower world and prevailed on the nether king by the spell he wielded to allow her to accompany him back, but on the condition that he must not, as she followed him, turn round and look; this condition he failed to fulfil, and he lost her again, but this time for ever; whereupon, as the story goes, he gave himself up to unappeasable lamentings, which attracted round him a crowd of upbraiding Mænades, who in their indignation took up stones to stone him and mangled him to death, only his lyre as it floated down the river seaward kept sounding “Eurydice! Eurydice!” till it was caught up by Zeus and placed in memorial of him among the stars of the sky.
