“ The Brieders, aftre like maner, learnyng the trade of their fathers, occupie their whole life therabout. We see also that al maner of Sciences haue bene much bettred, yea, brought to the toppe of perfection, emong the Egiptians. For the craftes men there, not medlyng with any commune matiers that mighte hindre theim, emploie them selues onely to suche sciences as the lawe doeth permit them, or their father hath taught them. So that thei neither disdaine to be taughte, nor the hatred of eche other, ne any thing elles withdraweth them from their crafte. ”
