Anytime I look at the printer’s mark I sigh with relief that this book was published by Hieronymus Froben and not by his father, Johann Froben.

Had it been printed during his father’s time, the book's trip to Pittsburgh might have never happened. Though Johann was cured from an illness by Swiss physician Paracelsus, he might not have been so grateful to the Swiss doctor had he been around to witness the destruction of his workshop at the hand of his very savior.  Paracelsus publicly burned the works of Galen in Basel in 1527 to make the point that he no longer considered him a medical authority. What a relief that the 1562 edition by Hieronymus Froben, published after this chilling event, was spared this fate.
