My attention was first drawn to the Oráculo Manual by Mr. (now Sir Mountstuart) Grant Duff’s admirable article on Balthasar Gracian in the Fortnightly Review of March 1877. I soon after obtained a copy of Schopenhauer’s excellent version, and during a journey in Spain I procured with some difficulty a villainously printed edition of Gracian’s works (Barcelona, 1734, “Por Joseph Giralt”), which contains the Oráculo Manual towards the end of the first volume (pp. 431-494).
