As an old Chronicle maketh mention. There was in the parts of Morea, a very good workman in stone: Who for y^e singular good skill he had in his Art, was called (as I take it) Maestro Chiarissimo. This man (now well strooken in yeares) made a certaine treatise, & therin gathered together al y^e precepts & rules of his arte: as the man y^t had very good skill to doe it: shewing in what sorte the proportions and lineaments of the body, should be duely measured, as well everyone a parte by it selfe, as one respecting another: y^t they might justly & duely be answerable y^e one to the other: which treatise of his, he named Regolo. Meaning to shewe, that according to that, all the Images and pictures, that from thensforth any workeman should make, should be squared & lined forth: as y^e beames, and y^e stones, and the walles, are measured by y^e rules & precepts of that booke. But, for that it is a muche easier matter to speake it, then to worke it, or doe it: and besides that, The greatest number of men, especially of us that be prophane and not learned, have our senses much quicker then our understanding, and consequently, better conceive particular things and Examples, then the generall propositions and Syllogismes (which I might terme in plainer speache, Reasons) for this cause this worthy man I speake of, having regard to the Nature of workemen: whose capacities are unfit and unable to weeld the weighte of generall Precepts and rules: and to declare more plainely, with all his cunning and skill: having found out for his purpose, a fine marble stone, with muche labour and paine, he fashioned and shaped an Image of it, as perfectly proportioned in every parte and member: as the precepts and rules of his treatise had before devised. And as he named the booke, so did he name that Image, and called it by name of Regolo. Now, (and it pleased god) I would I could but one parte of those twoe points, which that noble Ingraver & worckeman I speake of, had perfect skill and knowledge to doe: I meane, that I could gather together in this treatise, after a sorte, the due measures of this Art I take uppon me to treate of. For, to perfourme the other, to make the second Regolo: I meane, to use and observe in my maners, the measures I speake of, framing and forming, as it were, A Visible Example, and a material Image of them: it were now, to muche for me to doe. For asmuch as, It is not inough to have knowledge and Art, in matters concerning maners & fashions of men: But it is needefull withall, to worke them to a perfect effect, to practise and use them muche: which cannot be had uppon the soudaine, nor learned by & by: but it is number of yeares that must winne it: & y^e beste parte of mine be runne fourth alredy, you see.
