The Works of Galileo

A New Pope and a New Dialogue

The Oklahoma copy of the Dialogue

The annotion (Figure 1) says that this figure about falling bodies is upside down. That error is corrected in the second edition. This is Galileo’s handwriting, in his own copy of the book. (The handwriting was verified by Galileo scholar Stillman Drake.)

(Figure 2) shows a new sentence by Simplicio to go before a long paragraph by Salviati, again written in Galileo’s own hand. It is almost as if we were in his study, looking over Galileo’s shoulder, during the crucial months before his trial.

If you visit Oklahoma and hold this or one of the other books in this exhibit, you might be touching some of Galileo’s DNA. You would be holding the very book that he held in his hands. (Figure 3)
