The historian was looking for conceptual connections between Ptolemy and Galileo, but the discovery of Galileo’s handwriting in Ptolemy’s book seemed to be a surprise.

- 2b3a51 7mo agoOwen Gingerich was a historian of astronomy who did a census of printed early editions of Copernicus' book De revolutionibus. He found a tradition of students copying annotations from teachers readings into their own copies of the book. I recollect that he was able to trace various traditions of commentary each stemming from a well known astronomy teacher. I suppose that checking early printings of key works looking for annotations is a pretty standard thing to do now.
