William Petty,
The Advice to Hartlib
(1647)
“ And among these, we wish that the History of Arts or Manufactures might first be undertaken as the most pleasant and profitable of all the rest, wherein should be discribed the whole Processe of Manual Operations and Applications of one Naturall thing (which we call the Elements of Artificials) to another, with the necessarie Instruments and Machines, whereby every peice of worke is elaborated, and made to be what it is, unto which work bare words being not sufficient, all Instruments and tooles must be pictured, and colours added when the discriptions cannot be made intelligible without them. ”
