its beauteous landscape of hill and dale, darkling forest, dizzy cliffs,
and rushing river, at his feet, feebly cursing the unhappy city for its
ingratitude to an invisible and impotent sovereign; his excellent brother
Matthias meanwhile marauding through the realms and taking one crown
after another from his poor bald head.

It would be difficult to depict anything more precisely what an emperor
in those portentous times should not be. He collected works of art of
many kinds--pictures, statues, gems. He passed his days in his galleries
contemplating in solitary grandeur these treasures, or in his stables,
admiring a numerous stud of horses which he never drove or rode.
Ambassadors and ministers of state disguised themselves as grooms and
stable-boys to obtain accidental glimpses of a sovereign who rarely
granted audiences. His nights were passed in star-gazing with Tycho de
Brake, or with that illustrious Suabian whose name is one of the great
lights and treasures of the world. But it was not to study the laws of
planetary motion nor to fathom mysteries of divine harmony that the
monarch stood with Kepler in the observatory. The influence of countless
worlds upon the destiny of one who, by capricious accident, if accident
ever exists in history, had been entrusted with the destiny of so large a
portion of one little world; the horoscope, not of the Universe, but of
himself; such were the limited purposes with which the Kaiser looked upon
the constellations.

For the Catholic Rudolph had received the Protestant Kepler, driven from
Tubingen because Lutheran doctors, knowing from Holy Writ that the sun
had stood still in Ajalon, had denounced his theory of planetary motion.
His mother had just escaped being burned as a witch, and the world owes
a debt of gratitude to the Emperor for protecting the astrologer, when
enlightened theologians might, perhaps, have hanged the astronomer.
