While he aided our understanding of many aspect of Creation, he is best known for his contributions to astronomy. Based on a friend’s description of a Danish “spyglass,” Galileo made a telescope and used it in his study of the heavens. He discovered sunspots, the four largest moons of Jupiter, mountains and valleys on the moon, and most importantly, the phases of Venus. The moons of Jupiter as well as the phases of Venus supported the idea championed by Copernicus – that the earth orbited the sun, which sat at the center of the universe.
In an effort to communicate these things to other natural philosophers, he wrote a book entitled Dialogue Concerning the Two Chief World Systems. Even though it was accepted by two different Roman Catholic censors (one in Rome and one in Florence), it was eventually used by certain members of the Roman Catholic church to put him on trial. The ruling based on the trial declared that Galileo was:
…vehemently suspected of heresy, namely, of having believed and held the doctrine – which is false and contrary to the sacred and divine Scriptures – that the Sun is the center of the world and does not move from east to west and that the Earth moves and is not the center of the world…
As punishment, he was placed under house arrest for the remainder of his life.
(If you want a more detailed discussion of this saga, I have one here.)
The point, of course, is that the judgement rendered by the Roman Catholic church made his family hesitant to bury him where the rest of his family was buried – The Basilica of Santa Croce. They were afraid it would anger prominent people in the church, so he was buried in the Novitiate Chapel that is connected to the basilica. Nearly a hundred years later, however, his admirers were able to exert enough influence and spend enough money for the elaborate monument pictured at the beginning of this post, which is in a prominent place in the basilica. His body was exhumed and moved there in 1737.
One very interesting aspect of the tomb is its location. It is directly across from the tomb of Michelangelo, who died within a few days of Galileo’s birth. Some say that spot was chosen because there was a popular belief that Michelangelo’s spirit left his body and went to Galileo. I don’t know if that’s true, but I can say that the location indicates that his admirers wanted to tell the world that Galileo was a treasured son of Florence, as was the famous artist.
Another very interesting aspect to the tomb is that there are actually two bodies inside. One, of course, is the body of Galileo. The other is the body of his daughter, Sister Maria Celeste. When Galileo was exhumed, the body that was thought to be Galileo’s was actually that of a woman! Galileo’s body was found underneath the woman’s body. It turns out that his pupil, Vincenzo Viviani, had secretly buried his daughter there, apparently as a posthumous gift to him. As a result, both bodies now rest in the tomb.
One final thing that I find interesting is that when Galileo’s body was moved, his admirers took three fingers, a tooth, and a vertebra as “keepsakes.” The vertebra is kept at the University of Padua, where Galileo taught for many years. The tooth and fingers are on display in the Galielo museum in Florence. I couldn’t get a good shot of them because of glare, but here are the two containers that hold the bones. The brown, wooden container holds two fingers and the tooth. The glass container holds the middle finger.
While it might seem odd to you and me (my wife said, “disgusting”), bones of important people (usually saints) were commonly collected and often venerated. Once again, this is a symbol of how important Galileo was to many people.
