Galileo, the fat knight


Galileo was afflicted with a cold and crazy mother—after he made his first telescope, she tried to bribe a servant to betray its secret so that she could sell it on the market!—and some of the chauvinism that flecks his life and his writing may have derived from weird-mom worries. He was, however, very close to his father, Vincenzo Galilei, a lute player and, more important, a musical theorist. Vincenzo wrote a book, startlingly similar in tone and style to the ones his son wrote later, ripping apart ancient Ptolemaic systems of lute tuning, as his son ripped apart Ptolemaic astronomy. Evidently, there were numerological prejudices in the ancient tuning that didn’t pass the test of the ear. The young Galileo took for granted the intellectual freedom conceded to Renaissance musicians. The Inquisition was all ears, but not at concerts. Part of Galileo’s genius was to transfer the spirit of the Italian Renaissance in the plastic arts to the mathematical and observational ones. He took the competitive, empirical drive with which Florentine painters had been looking at the world and used it to look at the night sky.
