First, with a ruler, and a blacke lead plummet, draw a line at the very
top: also another at the bottome paralell, or equally distant from the
other: from the upper line, let fall two perpendicular or plum-lines
euen unto the lowermost line, so those foure lines will make a square:
now you must diuide this square into diuers equall parts, with a paire
of compasses, and draw lines with a ruler and blacke lead plummet,
quite over the picture: so the lesselines will divide the picture into
equall parts or squares: then take a faire paper, and make as many
squares upon it, as there is in the picture: you may make them as
little as you will, but be sure that they are equall, and of just
number with those in the picture. Having thus crossed your picture, and
drawne over your faire paper into squares, take a blacke lead pen, and
draw the picture by little and little, passing from square unto square,
untill you have finished the whole: still observing the order of the
squares as they stand in either: then draw it ouer with a pen, in which
second drawing of it over, you may easily mend any fault: when it is
dry, rub it over with the crum of white bread, and it will take off all
the blacke lead strokes, and your draught onely will remaine faire upon
the paper or parchment. Here I might have entred into discourse of
drawing paralels, perpendiculars, making of squares, and such like: but
to deal truely, I was as loth to trouble my selfe, as to wearie you:
you shall neede onely to provide a ruler of thin brasse or copper,
having a crosse thwart one end of it: the charge will not be much, nor
the use tedious: the figure followeth, noted A, B.

Let _a_, _b_, _c_, _d_, be a line given, whereon to erect a
perpendicular or plumb line: lay the ruler so, that the crosse over the
end of it, may lye full upon the Line, then draw a Line by the side of
the rule, and it is done.
