Because the Greeks and Romans used to engrave their laws and decrees on stone or metal, both in intaglio and relief, and even colored the depressed or prominent characters with various pigments, therefore the Greeks and Romans made use of printing and wood or metallic engraving--as understood in the present sense; that is to say, for the purpose of taking reversed impressions on paper, parchment, or the like, with ink or other pigments, from prepared blocks, or forms of movable types--the impressions, not the blocks or forms, being legible in the usual mode, from left to right, or the reverse, according to the nature of the character or language. It is, perhaps, scarcely necessary now to state, not only that there is no reason for believing that any ancient nation was acquainted at all with any thing in the least degree approaching to the modern art of printing, but that there is a positive certainty that no people of antiquity was so acquainted. In the same manner may be dismissed the Chinese claim to originality in this invention. So early as the 12th century, stamps, engraved with monograms, or fanciful figures, assumed by individuals as their signs manuals, wrought on them in relief, were in common use. They were made of wood or metal, dipped in ink or paint, and impressed on any document requiring signature; and they seem to have continued occasionally in use so late as to the reign of King Henry VIII. of England, whose warrant for the execution of the poet Surrey was signed by this method, and not by royal sign manual; the king being then in _articulo mortis_, and unable to sign his name. At a much earlier period than this--so early, indeed, as the sixth century--the Emperor Justin I., in signing documents, made use of what is now called a stencil, a thin plate of wood or metal perforated with figures, characters, or other designs, which, when applied to a surface of blank paper or parchment, leaves the design on the exposed surface of the paper, all else being covered, open to the operation of a brush or pencil, which necessarily leaves the impress of the form invariably the same on all occasions. From this practice of stenciling, perhaps, or more probably from the dipping of the signet-ring, which had been used for ages in impressing wax and the like, into ink, and impressing it on paper, was derived the idea of stamps engraved with monograms, and used as signatures--an invention of vast practical utility in an age when not one man of five hundred, even of kings and nobles, unless he were in holy orders, was capable of signing, or even reading, his own name. One of the earliest of these stamps is that of Gundisalvo Tellez, one of the Gothic invaders of Spain, affixed to a charter bearing date A. D. 840; and the same sign, after his death, was appended, by his widow, Flamula, to a grant for the good of her husband’s soul.
