This is one of Euler's more famous papers and a good example of his work in an area usually called "recreational mathematics." It was the first mathematical paper on knight's tours (A knight's tour is a path that a knight chesspiece can follow to visit every square on the chessboard without revisitng any sqaure.).

This paper, although presented in 1759, did not appear in print until 1766, and the first review of it, quoting his first two tours, appeared in the

According to C. G. J. Jacobi, a treatise with this title was presented to the Berlin Academy on March 2, 1758.
