[Footnote 342: From a memorial presented by these printers to Sixtus IV. in 1472 we ascertain some facts about their industry. They had at that date printed in all 12,495 volumes. It was their custom to issue 265 copies each edition; the double of that number for Virgil, Cicero's separate works, and theological books in request. Cantù, _Lett. It._ p. 112. See Cantù, p. 110, for details of the earliest Latin books.]
While scholars rejoiced in the art that, to quote the word of one of them, 'had saved the labour of their aching joints,' the copyists complained that their occupation would be taken from them. The whistle of the locomotive at the beginning of this century was not more afflicting to stage-coachmen than the creaking of the wooden printing press to those poor scribes. Yet, however quickly a labour-saving invention may spread, there is generally time for the superseded industry to die an easy death, and for artisans to find employment in the new trade. Vespasiano, who during twenty-six years survived the first book printed in Florence, could even afford to despise the press.[343] The great nobles, on whose patronage he depended, did not suddenly transfer their custom from the scribe to the compositor; nor was it to be expected that so essentially a democratic art as printing should find immediate favour with the aristocracy. A prince with a library of MSS. worth 40,000 ducats hated the machine that put an equal number of more readable volumes within the reach of moderate competency. Moreover, a certain suspicion of subversiveness and license clung about the press. This was to some extent justified by fact, since the press was destined to be the most formidable engine of the modern reason. Ecclesiastics, again, questioned whether the promiscuous multiplication of books were pious; and Alexander VI. stretched his hand out to coerce the printer's devil. To check the spread of printing would, however, have overtaxed the powers of any human tyranny. All that the Church could do was to place its productions under episcopal control.
Though the copyists of MSS. were thrown out of work by the printing press, it gave important stimulus to other industries in Italy. The paper mills of Fabriano and of Colle in the Val d'Elsa became valuable properties;[344] compositors and readers began to form a separate class of artisans, while needy scholars found a market for their talents in the houses of the publishers. When we consider the amount of literary work that had to be performed before Greek, Latin, and Hebrew texts could be prepared for the press, the difficulty of procuring correct copies of authoritative codices, and the scrupulous attention expended upon proof sheets, we are able to understand that men who lived by learning found the new art profitable.
