While these events were occurring, COSTAR, of Haarlem, was plodding on with the same "noble mystery," but only printing on one side of a leaf, not having yet discovered that a leaf might be contrived to contain two pages. The partisans of Costar assert that it was proved he substituted moveable for fixed letters, which was a giant's footstep in this new path. A faithless servant ran off with the secret. The history of printing abounds with such tales. Every step in the progress of the newly-invented art indicates its gradual accessions. The numbering of the pages was not thought of for a considerable time; the leaves were long only distinguished by letters or signatures--a custom still preserved, though apparently superfluous. There is something attractive for rational curiosity in the earliest beginnings of every art; every slight improvement, even though trivial, has its motive, and supplies some want. On this principle the history of punctuation enters into the history of literature. Caxton had the merit of introducing the Roman pointing as used in Italy; and his successor, Pynson, triumphed by domiciliating the Roman letter. The dash, or perpendicular line, thus, | was the only punctuation they used. It was, however, discovered that "the craft of poynting well used makes the sentence very light." The more elegant comma supplanted the long uncouth |; the colon was a refinement, "showing that there is more to come." But the semicolon was a Latin delicacy which the obtuse English typographer resisted. So late as 1580 and 1590 treatises on orthography do not recognise any such innovator; the Bible of 1592, though printed with appropriate accuracy, is without a semicolon; but in 1633 its full rights are established by Charles Butler's "English Grammar." In this chronology of the four points of punctuation it is evident that Shakspeare could never have used the semicolon--a circumstance which the profound George Chalmers mourns over, opining that semicolons would often have saved the poet from his commentators. FUST had bound his workmen to secrecy by the solemnity of an oath; but at the siege of Mentz that freemasonry was lost. These early printers dispersed, some were even bribed away. Two Germans set up their press in the monastery of Subiaco, in the vicinity of Naples, whose confraternity consisted of German monks. These very printers finally retreated to Rome for that patronage they had still to seek; and at Rome they improved the art by adopting the Roman character. Not only the invention of the art was progressive, but the art itself was much more so.
