A compact but prominent constellation,
marked by the fifth-brightest star in the sky, Vega.
Mythologically, Lyra was the lyre of the great musician
Orpheus, whose venture into the Underworld is one of the most
famous of Greek stories. It was the first lyre ever made,
having been invented by Hermes, the son of Zeus and Maia (one
of the Pleiades). Hermes fashioned the lyre from the shell of a
tortoise that he found browsing outside his cave on Mount
Cyllene in Arcadia. Hermes cleaned out the shell, pierced its
rim and tied across it seven strings of cow gut, the same as
the number of the Pleiades. He also invented the plectrum with
which to play the instrument.
Lyra was frequently visualized as an eagle or vulture as well as a lyre; both are shown on this engraving from the Uranographia of Johann Bode (1801). Near the tip of the vulture’s beak is the bright star Vega, here spelt Wega; Bode also gave it the alternative name Testa in reference to the tortoise shell from which the lyre was supposedly made by Hermes.
The lyre got Hermes out of trouble after a
youthful exploit in which he stole some of Apollo’s
cattle. Apollo angrily came to demand their return, but when he
heard the beautiful music of the lyre he let Hermes keep the
cattle and took the lyre in exchange. Eratosthenes says that
Apollo later gave the lyre to Orpheus to accompany his songs.
Orpheus was the greatest musician of his
age, able to charm rocks and streams with the magic of his
songs. He was even reputed to have attracted rows of oak trees
down to the coast of Thrace with the music of his lyre. Orpheus
joined the expedition of Jason and the Argonauts in search of
the golden fleece. When the Argonauts heard the tempting song
of the Sirens, sea nymphs who had lured generations of sailors
to destruction, Orpheus sang a counter melody that drowned the
Sirens’ voices.
Later, Orpheus married the nymph Eurydice.
One day, Eurydice was spied by Aristaeus, a son of Apollo, who
attacked her in a fit of passion. Fleeing from him, she stepped
on a snake and died from its poisonous bite. Orpheus was
heartbroken; unable to live without his young wife, Orpheus
descended into the Underworld to plead for her release. Such a
request was unprecedented. But the sound of his music charmed
even the cold heart of Hades, god of the Underworld, who
finally agreed to let Eurydice accompany Orpheus back to the
land of the living on one solemn condition: Orpheus must not at
any stage look behind him until the couple were safely back in
daylight.
Orpheus readily accepted, and led Eurydice
through the dark passage that led to the upper world, strumming
his lyre to guide her. It was an unnerving feeling to be
followed by a ghost. He could never be quite sure that his
beloved was following, but he dared not look back. Eventually,
as they approached the surface, his nerve gave out. He turned
around to confirm that Eurydice was still there – and at
that moment she slipped back into the depths of the Underworld,
out of his grasp for ever.
Orpheus was inconsolable. He wandered the
countryside, plaintively playing his lyre. Many women offered
themselves to the great musician in marriage, but he preferred
the company of young boys.
There are two accounts of the death of
Orpheus. One version, told by Ovid in his Metamorphoses, says that the
local women, offended at being rejected by Orpheus, ganged up
on him as he sat singing one day. They began to throw rocks and
spears at him. At first his music charmed the weapons so that
they fell harmlessly at his feet, but the women raised such a
din that they eventually drowned the magic music and the
missiles found their mark.
Eratosthenes, on the other hand, says that
Orpheus incurred the wrath of the god Dionysus by not making
sacrifices to him. Orpheus regarded Apollo, the Sun god, as the
supreme deity and would often sit on the summit of Mount
Pangaeum awaiting dawn so that he could be the first to salute
the Sun with his melodies. In retribution for this snub,
Dionysus sent his manic followers to tear Orpheus limb from
limb. Either way, Orpheus finally joined his beloved Eurydice
in the Underworld, while the muses put the lyre among the stars
with the approval of Zeus, their father.
Ptolemy knew the constellation’s
brightest star simply as Lyra. The name we use for this star
today, Vega, comes from the Arabic words al-nasr al-waqi’ that
can mean either ‘the swooping eagle’ or
‘vulture’, for the Arabs saw an eagle or vulture
here. The constellation was often depicted on star maps as a
bird positioned behind a lyre, as on the illustration here. It
seems that the Arabs visualized Vega and its two nearby stars
Epsilon and Zeta Lyrae as an eagle with folded wings, swooping
down in its prey, whereas in the constellation Aquila the star
Altair and its two attendant stars gave the impression of a
flying eagle with wings outstretched.
Beta Lyrae is called Sheliak, a name that
comes from the Arabic for ‘harp’, in reference to
the constellation as a whole. Beta Lyrae is a celebrated
variable star. Gamma Lyrae is called Sulafat, from the Arabic
meaning ‘the tortoise’, after the animal from whose
shell Hermes made the lyre. Between Beta and Gamma Lyrae lies
the Ring Nebula, often pictured in astronomy books; it is a
shell of gas thrown off by a dying star.
