Judging from the manner in which the origin and history of Playing Cards have been treated by various authors within the last hundred and fifty years, it is evident that the subject, whatever they may have made of it, is one of great "capability," to use the favorite term of a great designer in the landscape-gardening line; and it seems no less evident that some of those authors have been disposed to magnify its apparent insignificance by associating it with other topics, which are generally allowed to be both interesting and important. In this respect they have certainly shown great _tact_; for though many learned men have, at different periods, written largely and profoundly on very trifling subjects, yet it does seem necessary for a man, however learned and discreet, to set forth, either in his title-page or in his proemium, something like an apology for his becoming the historiographer of Playing Cards,--things in themselves slightly esteemed even by those who use them most, and frequently termed by pious people "the devil's books." The example which has thus been set I am resolved to follow; for though, in the title-page, I announce no other topic for the purpose of casting a borrowed light on the principal subject, I yet wish the reader to understand that I am writing an apology for it now; and in the progress of the work I doubt not that I shall be found as discursive as most of those who have previously either reasoned or speculated on Playing Cards. A history of Playing Cards, treating of them in all their possible relations, associations, and bearings, would form nearly a complete cyclopædia of science and art; and would still admit of being further enlarged by an extensive biographical supplement, containing sketches of the lives of celebrated characters who have played at cards,--or at any other game. CARDS would form the centre--the _point_, having position, but no space,--from which a radius of indefinite extent might sweep a circle comprehending not only all that man knows, but all that he speculates on. The power of reach, by means of the point and the radius, being thus obtained, the operator has his choice of topics; and can arrange them round his centre, and colour them at his will, as boys at school colour their fanciful segments of a circle. To exemplify what has just been said about the capability of cards as a subject of disquisition:--One writer, Père Menestrier,[1] preluding on the invention of cards, says, _apropos_ to the term JEU--_ludus_, a game--that, to the Supreme Being the creation of the world was only a kind of game; and that schoolmasters with the Romans were called Ludi Magistri--masters of the game or sport. Here, then, is a fine opportunity for a descant on creation; and for showing that the whole business of human life, from the cradle to the grave, is but a game; that all the world is a great "gaming-house,"--to avoid using a word offensive to ears polite,--
