Instead of having previous editions to work upon, the publishers were obliged, in the first instance, to collect MSS. For this purpose they either travelled themselves from city to city, or employed competent amanuenses. Next, it was necessary to study the philosophers, poets, historians, mathematicians, and mystics, whose works they intended to print, in order that no mistake in the sense of the words should be made. Orthography and punctuation had to be fixed; and between many readings only one could be adopted. Giving a first edition to the world involved far more anxiety on these points than the reproduction of a book already often printed. No one man could accomplish such tasks alone. Therefore we find that scores of learned men were associated together for the purpose, living under the same roof, revising the copy for the compositor, overlooking the men at work, reading the text aloud, and correcting the proofs with a vigilance that is but little needed nowadays. All this labour, moreover, was accomplished without the aid of grammars, lexicons, and other aids. Truly we may say without exaggeration that the Aldi of Venice and the Stephani of Paris are more worthy of commemoration for services rendered through scholarship to humanity than those modern castigators of ancient texts, the Porsons and the Lachmanns, whose names are on every lip. The enthusiasm of discovery, and the rich field for original industry offered to those early editors, may be reckoned as compensation for their otherwise overwhelming toil.
