Orion /ori-on/ [2 sylls.] as a boys' name is pronounced oh-RYE-on. It is of Greek origin. Greek mythology: Orion was a mighty hunter, the son of Poseidon, who was turned into a constellation. The Orion constellation contains three of the most conspicuous stars in the nighttime sky.
Lyre (Lyra). This constellation, put in the sky by the MUSES, represents the lyre made by Hermes and given to Orpheus by either Hermes or Apollo after the latter had invented the cithara. Others say this is the lyre of Theseus (Ara.Phae.269; Hyg.Ast.2.6, 2.7; Man.1.325).
