history of the Aryan race, and the rays of Regulus bring again the
dreams of Babylon and Nineveh, of Greece and Rome, of India, and of
the star-watching deserts of Arabia. Cyrus, in his conquering marches,
may have looked to that star for help and inspiration, for it was the
heavenly guardian of the Persian monarchs.
The spectroscope tells us that Regulus, like Spica, is approaching
us, but less rapidly, drawing nearer about 475,000 miles per day. But
its distance is 950,000,000,000,000 miles (parallax 0″.02), and it
outshines the sun one thousand times.
The second star above Regulus, in the curve of the sickle’s blade,
is Gamma (γ), or _Algieba_ (Arabic the “Forehead”), a beautiful
double, probably binary, with a period of revolution which Doberck has
estimated at about four hundred years. The larger star of the pair is
golden-orange and the smaller bronze-green, a marvellous contrast, and
an ordinary telescope shows well the spectacle, the distance between
the components being 3″.78. And this wonderful pair is rushing toward
the solar system at the rate of _two million miles per day_. Yet so
great is its distance that we have no record that in a thousand years
men have noticed a brightening of the headlight of this terrible
locomotive of space! But probably the more refined methods of the
present time, if applied for a similar period, would reveal an ominous
expansion of that oncoming light. Gamma is interesting as marking,
roughly, the spot in the sky which was the apparent centre of radiation
for the November meteors, which were last seen in their splendor in
1866-67, their return in 1899-1900, for which the world had long been
waiting, having been prevented by the disturbing attraction of Jupiter
and Saturn, which shifted their orbit.
The “Sickle” in its entirety is an attractive asterism, and hanging so
conspicuously in the sky on a spring evening it may be imaginatively
regarded as a harbinger of the opening of the season when the thoughts
of men are turning to preparations for future harvests. In the height
of the harvest season the “Sickle” sets near sundown, then no longer
standing upright, but lying along upon the horizon--a symbol of the
wearied husbandman’s approaching hours of rest:
“Nor shall a starry night his hopes betray.”
Away off at the eastern end of the constellation, in the lion’s tail,
shines its second star in rank, Denebola (Arabic _Al Dhanab_, the
“Tail”). It too is speeding hitherward, but only half as fast as Gamma.
Like Aldebaran, the name Denebola has an indefinite charm, from its
full round vowel sounds, and a certain nobility in the look of it as
it lies on the printed page. As with many sonorous Indian names in
American geography, these old star names lose something of their effect
when they are translated. It is better to take them as they stand,
transcending terrestrial analogy and definition, like the sublime
objects that they designate.
