Virgo is the second-largest constellation
in the sky, exceeded only by the much fainter Hydra. The Greeks
called the constellation Parthenos. She is usually identified
as Dike, goddess of justice, who was daughter of Zeus and
Themis; but she is also known as Astraeia, daughter of Astraeus
(father of the stars) and Eos (goddess of the dawn). Virgo is
depicted with wings, reminiscent of an angel, holding an ear of
wheat in her left hand (the star Spica).
Dike features as the impartial observer in
a moral tale depicting mankind’s declining standards. It
was a favourite tale of Greek and Roman mythologists, and its
themes still sound familiar today.
Virgo depicted in the Atlas Coelestis of John Flamsteed. In her right hand she carries a palm frond, while in her left hand she holds an ear of wheat marked by the bright star Spica.
Dike was supposed to have lived on Earth in
the Golden Age of mankind, when Cronus ruled Olympus. It was a
time of peace and happiness, a season of perennial spring when
food grew without cultivation and humans never grew old. Men
lived like the gods, not knowing work, sorrow, crime or war.
Dike moved among them, dispensing wisdom and justice.
Then, when Zeus overthrew his father Cronus
on Olympus, the Silver Age began, inferior to the age that had
just passed. In the Silver Age, Zeus shortened springtime and
introduced the yearly cycle of seasons. Humans in this age
became quarrelsome and ceased to honour the gods. Dike longed
for the idyllic days gone by. She assembled the human race and
spoke sternly to them for forsaking the ideals of their
ancestors. ‘Worse is to come’, she warned them.
Then she spread her wings and took refuge in the mountains,
turning her back on mankind. Finally came the Ages of Bronze
and Iron, when humans descended into violence, theft and war.
Unable to endure the sins of humanity any longer, Dike
abandoned the Earth and flew up to heaven, where she sits to
this day next to the constellation of Libra, which some see as
the scales of justice.
There are other goddesses who can claim
identity with Virgo. One is Demeter, the corn goddess, who was
daughter of Cronus and Rhea. By her brother Zeus she had a
daughter, Persephone (also called Kore, meaning
‘maiden’). Persephone might have remained a virgin
for ever had not her uncle, Hades, god of the Underworld,
kidnapped her while she was out picking flowers one day at
Henna in Sicily. Hades swept her aboard his chariot drawn by
four black horses and galloped with her into his underground
kingdom, where she became his reluctant queen.
Demeter, having scoured the Earth for her
missing daughter without success, cursed the fields of Sicily
so that the crops failed. In desperation she asked the Great
Bear what he had seen, since he never sets, but since the
abduction had taken place during the day he referred her to the
Sun, who finally told her the truth.
Demeter angrily confronted Zeus, father of
Persephone, and demanded that he order his brother Hades to
return the girl. Zeus agreed to try; but already it was too
late, because Persephone had eaten some pomegranate seeds while
in the Underworld and, once having done that, she could never
return permanently to the land of the living. A compromise was
reached in which Persephone would spend half (some say
one-third) of the year in the Underworld with her husband, and
the rest of the year above ground with her mother. Clearly,
this is an allegory on the changing seasons.
Eratosthenes offers the additional
suggestion that Virgo might be Atargatis, the Syrian fertility
goddess, who was sometimes depicted holding an ear of corn. But
Atargatis is identified with the constellation Piscis
Austrinus. Hyginus equates Virgo
with Erigone, the daughter of Icarius, who hanged herself after
the death of her father. In this story, Icarius became the
constellation Boötes, which adjoins Virgo to the north,
and Icarius’s dog Maera became the star Procyon (see Boötes and Canis Minor).
Eratosthenes and Hyginus both name Tyche,
the goddess of fortune, as another identification of Virgo; but
Tyche was usually represented holding the horn of plenty
(cornucopia) rather than an ear of grain. In the sky, the ear
of corn is represented by the first-magnitude star Spica, Latin
for ‘ear of grain’ (the name in Greek, Stachys, has
the same meaning).
Beta Virginis is called Zavijava, from an
Arabic name meaning ‘the angle’; in the Almagest, Ptolemy
located this star on the top of Virgo’s left wing. Gamma
Virginis, also in the left wing, is called Porrima, after a
Roman goddess. According to Ovid in his Fasti, Porrima and her
sister Postverta were the sisters or companions of the
prophetess Carmenta. Porrima sang of events in the past, while
Postverta sang of what was to come.
Epsilon Virginis, on Virgo’s right
wing, is named Vindemiatrix, from the Latin meaning
‘grape-gatherer’ or ‘vintager’, because
its first visible rising before the Sun in August marked the
beginning of each year’s vintage. Ovid in his Fasti tells us
that this star commemorates a boy named Ampelus (the Greek word
for ‘vine’) who was loved by Dionysus, god of wine.
While picking grapes from a vine that trailed up an elm tree,
Ampelus fell from a branch and was killed; Dionysus placed him
among the stars. This star’s Greek name, Protrygeter,
also means ‘grape gatherer’. Its importance as a
calendar star is demonstrated by the fact that it was one of
the few stars named by Aratus and, at third magnitude, was far
fainter than the others.
In Chinese astronomy, two chains of five
stars beginning in Virgo and running into neighbouring
constellations were visualized as the boundary walls of an area
called Taiwei, a court or palace of the Emperor, where the Privy
Council met in camera for administrative and legal discussions. One
chain started with Eta Virginis and continued northwards via
Gamma (Porrima), Delta and Epsilon Virginis (Vindemiatrix) to
Alpha Comae Berenices. The other chain started at Beta Virginis
(Zavijava) and ran into Leo, ending at Delta Leonis. Within Taiwei, in the area we
would now consider the “bowl” of Virgo, various
faint stars were seen as representing groups of officials and
dignitaries such as Sangong (seats for three excellencies), Jiuqing (seats for
nine ministers, although it consisted of only three stars), and
Yezhe, a
court usher. Others were in present-day Leo.
The gap between Beta and Eta Virginis was
seen as a gateway into Taiwei. Spica and Zeta Virginis formed Jiao, the horn of the
Blue Dragon cang long. Jiao was also the first of the 28 Chinese lunar
mansions, or xiu. Since the ecliptic passed between the two stars of Jiao the pair were
seen as a gateway for the Sun, Moon and planets (there are many
such walls, gateways and courts in the Chinese sky). At right
angles to the line between Spica and Zeta Virginis, two other
stars, identities uncertain but close to the ecliptic, formed Pingdao, a flat,
straight road for the Sun, Moon and planets. Confusingly, two
stars to the south of Spica, 53 and 69 Virginis, were also
described as a gate, Tianmen, even though they were aligned parallel to the
ecliptic and so the Sun could not pass between them. To the
north of Zeta Virginis, two stars (Tau and either 78 or Sigma
Virginis) were Tiantian, the heavenly fields, in which the Emperor
instituted ploughing every spring before the year’s crops
were sown.
The stars Lambda, Kappa, Iota and Phi
Virginis formed Kang, the neck of the Blue Dragon, which gave its
name to the second lunar mansion. Kang was visualized in a second way more
relevant to Chinese society, as a government department
administering various home affairs.
