while Hermes had invented the lyre, Orpheus perfected it. Poets such as Simonides of Ceos said that Orpheus's music and singing could charm the birds, fish and wild beasts, coax the trees and rocks into dance, and divert the course of rivers. Orpheus was one of the handful of Greek heroes to visit the Underworld and return; his music and song had power even over Hades. The earliest known reference to this descent to the underworld is the painting by Polygnotus (5th century BC) described by Pausanias (2nd century AD), where no mention is made of Eurydice. Euripides and Plato both refer to the story of his descent to recover his wife, but do not mention her name; a contemporary relief (about 400 BC) shows Orpheus and his wife with Hermes. The elegiac poet Hermesianax called her Agriope; and the first mention of her name in literature is in the Lament for Bion (1st century BC) Some sources credit Orpheus with further gifts to humankind: medicine, which is more usually under the auspices of Asclepius (Aesculapius) or Apollo; writing, which is usually credited to Cadmus; and agriculture, where Orpheus assumes the Eleusinian role of Triptolemus as giver of Demeter's knowledge to humankind. Orpheus was an augur and seer; he practiced magical arts and astrology, founded cults to Apollo and Dionysus and prescribed the mystery rites preserved in Orphic texts. Pindar and Apollonius of Rhodes place Orpheus as the harpist and companion of Jason and the Argonauts. Orpheus had a brother named Linus, who went to Thebes and became a Theban. He is claimed by Aristophanes and Horace to have taught cannibals to subsist on fruit, and to have made lions and tigers obedient to him. Horace believed, however, that Orpheus had only introduced order and civilization to savages. Strabo (64 BC – c. AD 24) presents Orpheus as a mortal, who lived and died in a village close to Olympus. "Some, of course, received him willingly, but others, since they suspected a plot and violence, combined against him and killed him." He made money as a musician and "wizard" – Strabo uses (), also used by Sophocles in Oedipus Tyrannus to characterize Tiresias as a trickster with an excessive desire for possessions. () most often meant charlatan and always had a negative connotation. Pausanias writes of an unnamed Egyptian who considered Orpheus a (), i. e., magician. "Orpheus...is repeatedly referred
