**inventor**, **inventor** **of** **the** **first** **method** **of** **resolving** **biquadratic** **equations**, was born at Bologna about
1520. He studied mathematics under the celebrated Cardan, who, having had a problem given him lor solution,
gave it his pupil as an exercise of his ingenuity; and this
led to the discovery of a new method of analysis, which is
precisely that of biquadratics. Cardan published this method, and assigned the invention to its real author, who,
had it not been for this liberal conduct of the master, would
have been unknown to posterity. At the age of eighteen
he was appointed a tutor in arithmetic, and was equal to
the task of disputing with the most distinguished mathematicians of his own age. He was afterwards appointed
professor of mathematics at Bologna, where he died in
1565. Ferrari, although, like many other learned men of
his age, addicted to astrology, was an excellent classical
scholar, a good geographer, and well versed in the principles of architecture.
