The differences between the two men were pronounced. Galileo was an urbane gentleman who loved wine (which he described as "light ...held together by moisture"), women (he had three children by his mistress, Marina Gamba), and song (he was an accomplished musician). Kepler sneezed when he drank wine, had little luck with women, and heard his music in the stars. The deep organ-tones of religiosity and mysticism that resounded through Kepler's work struck Galileo as anachronistic and more than a bit embarrassing. Kepler suspected as much and pled with Galileo to please "not hold against me my rambling and my free way of speaking about nature." Galileo never answered his letter.LESSATTRIBUTION DETAIL »
