erature, and
was initiated into all the learning of the times. Music, drawing, and
painting were the occupations of his leisure hours; and such was his
proficiency in these arts, that he was reckoned a skilful performer on
several musical instruments, especially the lute; and his knowledge of
pictures was held in great esteem by some of the best artists of his
day.

Galileo seems to have been desirous of following the profession of a
painter: but his father had observed decided indications of early
genius; and, though by no means able to afford it, he resolved to send
him to the university to pursue the study of medicine. He accordingly
enrolled himself as a scholar in arts at the university of Pisa, on the
5th of November, 1581, and pursued his medical studies under the
celebrated botanist Andrew Caesalpinus, who filled the chair of medicine
from 1567 to 1592.

In order to study the principles of music and drawing, Galileo found it
necessary to acquire some knowledge of geometry. His father seems to
have foreseen the consequences of following this new pursuit, and though
he did not prohibit him from reading Euclid under Ostilio Ricci, one of
the professors at Pisa, yet he watched his progress with the utmost
jealousy, and had resolved that it should not interfere with his medical
studies. The demonstrations, however, of the Greek mathematician had too
many charms for the ardent mind of Galileo. His whole attention was
engrossed with the new truths which burst upon his understanding; and
after many fruitless attempts to check his ardour and direct his
thoughts to professional objects, his father was obliged to surrender
his parental control, and allow the fullest scope to the genius of his
son.

From the elementary works of geometry, Galileo passed to the writings of
Archimedes; and while he was studying the hydrostatical treatise[3] of
the Syracusan philosopher, he wrote his essay on the hydrostatical
balance,[4] in which he describes the construction of the instrument,
and the method by which Archimedes detected the fraud committed by the
jeweller in the composition of Hiero's crown. This work gained for its
author the esteem of Guido Ubaldi, who had distinguished himself by his
mechanical and mathematical acquirements, and who engaged his young
friend to investigate the subject of the centre of gravity in solid
bodies. The treatise on this subject, which Galileo presented to his
patron, proved the source of his f
