REEK LEGENDrecords that a
teenager named Phaethon, who
was raised by his mother, found
out that he was the son of Apollo the sun
god. Phaethon celebrated by taking the
family vehicle for a joyride. Said vehicle was
the fiery chariot in which Apollo rode from
sunrise to sunset, and Phaethon couldn’t
handle it. In a matter of hours, the reckless
youth managed to scorch both heaven and
earth. The chief god Zeus was not amused.
He corrected the chariot’s trajectory, then
zapped Phaethon with a thunderbolt and
dropped him into the nearest river.
Enter Cygnus, Phaethon’s best friend.
Cygnus was horrified but could do little
more than plunge into the water to retrieve
his buddy’s charred remains. The heroic
act did not go unnoticed. The gods trans-
formed Cygnus into a swan and elevated
him to the Milky Way. The location is
appropriate, for the band of the Milky Way
is said to be the glittering path created by
Phaethon during his wild ride across the
heavens. Needless to say, the impetuous
Phaethon was notplaced among the stars.
The basic outline of Cygnus is established

by a well-known asterism called the North-
ern Cross. The top of the cross is emblazoned
by first-magnitude Alpha Cygni, or Deneb
(“tail”). At the other end is third-magnitude
Beta, or Albireo. The name isn’t easily trans-
latable, but it marks the head of our long-
necked bird. Between those stars, at the cen-
tre of the cross, is second-magnitude Gamma,
or Sadr (“breast”). Sadr is flanked by 2.5-
magnitude Epsilon, or Gienah (“wing”), and
third-magnitude Delta, the only star in the
Northern Cross without a proper name.
Another myth concerning Cygnus un-
derscores the fact that the constellation
makers of long ago didn’t think much about
gender balance. The salacious story told
how Zeus disguised himself as a swan to
seduce Queen Leda of Sparta. Leda pro-
duced children for both her husband King
Tyndareus and her feathery lover Zeus.
Among the brood were the famous twins
Castor and Pollux, the former a mortal son
of Tyndareus and the latter an immortal
son sired by Jupiter. Typical of classical
mythology, Castor, Pollux and Cygnus were
all symbolized in the night sky, whereas
Leda is nowhere to be found. ✦
