rt of Hermias, a former
pupil, now King of Atarneus.

He remained here long enough to marry the niece of his patron, and
doubtless saw himself settled for life--a kingly crown within his reach
should his student-sovereign pass away.

And the royal friend did pass away, by the dagger's route. As
life-insurance risks I am told that Kings have to pay double premium.
Revolution broke out, and as Aristotle was debating in his mind what
course to pursue, a messenger with soldiers arrived from King Philip of
Macedon, offering safe convoy, enclosing transportation, and asking that
Aristotle come and take charge of the education of his son, Alexander,
aged thirteen.

Aristotle did not wait to parley: he accepted the invitation. Horses
were saddled, camels packed and that night, before the moon arose, the
cavalcade silently moved out into the desert.

The offer that had been made twenty-four years before, by Philip's
father, was now accepted. Aristotle was forty-two years old, in the
prime of his power. Time had tempered his passions, but not subdued his
zest in life. He had the curious, receptive, alert and eager mind of a
child. His intellect was at its ripest and best. He was a lover of
animals, and all outdoor life appealed to him as it does to a growing
boy. He was a daring horseman, and we hear of his riding off into the
desert and sleeping on the sands, his horse untethered watching over
him. Aristotle was the first man to make a scientific study of the
horse, and with the help of Alexander he set up a skeleton, fastening
the bones in place, to the mighty astonishment of the natives, who
mistook the feat for an attempt to make a living animal; and when the
beast was not at last saddled and bridled there were subdued chuckles of
satisfaction among the "hoi polloi" at the failure of the scheme, and
murmurs of "I told you so!"

Eighteen hundred years were to pass before another man was to take up
the horse as a serious scientific study; and this was Leonardo da Vinci,
a man in many ways very much like Aristotle. The distinguishing feature
in these men--the thing that differentiates them from other men--was the
great outpouring sympathy with every living creature. Everything they
saw was related to themselves--it came very close to them--they wanted
to know more about it. This is essentially the child-mind, and the
calamity of life is to lose it.
