Once upon a time, as a magnate of the city of Haarlem was walking in a wood near the city, he idly cut some letters on the bark of a beech tree. It then suddenly occurred to him that these letters might be impressed upon paper; whereupon he made some impressions of them for the amusement of his grandchildren. This, we have learned from our youth up, is how the art of printing came to be discovered. But unfortunately, this legend is not to be relied upon. As a matter of fact, the first inventor of printing is unknown, and even as regards moveable types it is impossible to say with absolute certainty when or by whom the idea was first conceived. Daunon, in his _Analyse des Opinions diverses sur l'origine de l'Imprimerie_, tells us that no less than fifteen towns claim to be the birthplace of printing, and that a still larger number of persons have been put forward as its inventors, from Saturn, Job, and Charlemagne downwards. The arguments for or against the pretensions of Saturn, Job, and Charlemagne, and, indeed, of the majority of the personages whose names have been mentioned in this connection, do not call for notice. For although the first printer is not known, many believe that they can point him out with tolerable certainty, and in the fierce battle which has raged round the question of the identity of the inventor of moveable types, two names alone have been used as the respective war-cries of the opposing armies. One is Johann Gutenberg of Mentz, and the other, Laurenz Coster of Haarlem.
