The five hundredth birthday of anything calls for a celebration. Certainly the five hundredth anniversary of a book as extraordinary as the Michigan Law Library's copy of the Argentoratene edition (so called from the Latin name of the city of Strassbourg where the book was printed) of Gratian's Decretum calls for some sort of memorial. Kenneth Boyce's piece, which follows this one, tells something about the book itself, where it came from and how it got to Michigan. This piece deals with its contents.
