From the Folger Library exhibit in early 2017, 500 Years of Treasures from Oxford.

Top Photo:  Galileo Galilei, Starry Messenger, 1610.  First Observations of the Moon's Surface.

Bottom Photo:  Hevelius, Selenographia, 1647:  "In this Description of the Moon, the author writes somewhat dismissively of Galileo's Starry Messenger, and looking at the two books side by side it is easy to see why.  In comparision with the latter [top photo to bottom photo], published a few decades earlier, the difference in the detail between the two diagrams of the Moon's surface is astonishing: an indication of the pace at which science was advancing in the first half of the 17th Century."  [quoted from the exhibition catalog]
