Bruno was born in 1548 in the town of Nola near Naples. At the age of 17, he entered the Dominican Order at the monastery of San Domenico Maggiore in Naples, taking the name Giordano, after Giordano Crispo, his metaphysics tutor. He continued his studies there, completing his novitiate, and ordained a priest in 1572 at age 24. During his time in Naples, he became known for his skill with the art of memory and on one occasion traveled to Rome to demonstrate his mnemonic system before Pope Pius V and Cardinal Rebiba. His great memory is what initially gained him attention.
He later became known for his cosmological theories which incorporated the sun centric model of Copernicus. He forced this model to its logical conclusions suggesting that stars were distant suns surrounded by their own planets. He even raised the possibility that these planets might foster life of their own. He also insisted that the universe is infinite and could have no center.
An invitation in 1592 to go to Venice to teach Count Giovanni Mocenigo the science of memory led to his downfall. Mocenigo in short order turned him over to the Inquisition on a charge of heresy.
After a nine-month trial, the Venice court sent him to Rome where he was imprisoned and underwent another trial that lasted seven years. He was convicted with the Pope's approval and sentenced to death by burning on Feb. 9, 1600.
The inquisition cardinals who judged Giordano Bruno were Cardinal Bellarmino (Bellarmine), Cardinal Madruzzo (Madruzzi), Camillo Cardinal Borghese (later Pope Paul V), Domenico Cardinal Pinelli, Pompeio Cardinal Arrigoni, Cardinal Sfondrati, Pedro Cardinal De Deza Manuel and Cardinal Santorio (Archbishop of Santa Severina, Cardinal-Bishop of Palestrina). Many of these would also be involved in the later trial of Galileo.
