GiordanoBruno:Philosopher/Heretic

Ingrid D. Rowland. Farrar, Straus & Giroux, $27 (335pp) ISBN 9780-8090-95-24-7

You sometimes hear the name Giordano Bruno (1548–1600) invoked as a prequel to the life of Galileo Galilei (1564–1642). These two natural philosophers, countrymen of the Italian peninsula, stood ready to shove the Earth from its ancient resting place and set it in orbit around the Sun. Though a rotating, revolving Earth challenged common sense and flew in the face of received wisdom, still they both embraced the idea—at their peril. The difference is that Bruno died for his beliefs (tied to a stake and set on fire in a public square in Rome), while Galileo recanted before the Inquisition and lived to advanced old age under house arrest. Legend connects their destinies, reducing Bruno's awful immolation to a cautionary tale that warns Galileo against too vigorous a defense of the dangerous new astronomy.

But, as Ingrid Rowland makes clear in her probing, thoughtful biography, Bruno's support for the Sun-centered cosmos paled next to the rest of his crimes. He was a true heretic by the Catholic Church's definition, for he doubted the divinity of Jesus, the virginity of Mary and the transubstantiation of the Communion wafer into the body of Christ. Protestants—among whom Bruno lived for a time in Switzerland, France, Germany and England—also branded him a heretic, since he was, after all, a professed priest of the Dominican order. Bruno managed, in the span of his 52 years, to be excommunicated twice—from the Calvinist Church as well as the Catholic.

Rowland identifies Bruno in her subtitle as philosopher and heretic. Her full text rounds out the list of his many other deserved epithets, including poet, playwright, private tutor, professor of sacred theology, linguist, master of the art of memory, even copy editor.

As a philosopher, Bruno went far beyond the Sun-centered cosmology of Nicolaus Copernicus (1473–1543). Apparently the first man to envision infinity, Bruno posited an “endlessly renewed and recreated universe.” Its limitless expanses of space knew no particular center, but contained innumerable suns, circled by a plurality of earths—and every one of them inhabited.

Rowland's own translations of Bruno's many works, including On the Immense and the Numberless , add immeasurably to her portrait of him. In 1581 he described himself as having “the look of a lost soul... for the most part you'll see him irritated, recalcitrant, and strange, content with nothing, stubborn as an old man of eighty, skittish as a dog that has been whipped a thousand times, a weepy onion eater.”

“He came into the world to light a fire,” Rowland acknowledges of her subject. That he did, and in the end it consumed him. 8 pages of b&W illus. (Aug.)
