Some Early Topological Puzzles - Part 2
David Singmaster
For some time, I considered the 1723-1725 edition of Ozanam's Récréations mathématiques et physiques as the first book to cover topological puzzles in detail and I only knew of a few earlier examples. Ozanam certainly gives many more examples than any previous book.  In the last few years, I have discovered some early sources which show several topological puzzles as being considerably older than I previously knew.  Here I show them.
