The letters which are usually called “text,” or quadrate, it was formerly customary so to write, although they are now imitated by the new art, as presently I shall show below. Although the alphabet begins with the writing of A, yet shall I (not needlessly) in the first place undertake to draw an I; because almost all the other letters are formed after this letter, although always something has to be added to it or taken away.
First make your I of equal squares, of which three are properly set one over the other; and the top of the top one, and the bottom of the bottom one, divide in two points, that is to say, into three equal parts: then set a square equal to the others in an oblique manner, so that its diagonal be vertical, and its angle on the first point of the top square. In this way, this oblique square shall extend with its angles more to the left than the right. Then produce upwards on either side, after the width of the superposed squares, right lines to meet the sides of the oblique set square. Next do below precisely as you did above, except that you must set the angle of the oblique square on the second point, that is, the one farthest to the right in the bottom of the lowest square; and let fall your lines on either side upon the transposed square: so will I be perfect; only above it draw with a fine pen a tiny in-crescent.
So shall you make N from two standards of this same I, set so that their angles at top and bottom touch; and in this manner the space between the two shall be narrower than the breadth of either: also, you shall no longer put little crescents above them; you must make of the same length all the short letters throughout the alphabet.
In like manner make M of three standards, just as you made N of two.
R make as I, except only that at top you must set an equal square diagonally, to the right, so that angle touch angle. R you may make also in this fashion: below leave its foot as before, but above add two diagonal squares, which shall touch each other with their angles in the middle point of the vertical limb, and then produce upwards both sides of the latter to meet the diagonal square.
V is made in three ways. First let it be made simply, as N; only that in the farther limb, you shall omit at the top the diagonal square; and instead shall draw an oblique line, so that it may make two angles in this limb (produced) of which the farther shall be of the same height as that of the topmost angle of the diagonal square, & the higher angle of the same height as the angle nearest to it in the said square.
The second V, which we use at the beginning of a sentence, make thus: Draw the first limb as before for I; only, at the bottom, push the diagonal square a little further to the right, so that its hither angle does not project beyond the side of the vertical limb, but falls in the line of its descent. Then set the second limb to the right of this, and cut it off below by an oblique line, drawn from the lowest angle upwards to the right, as far as the middle point of the lowest of the three superposed squares.
Next make W (i. e., double V) just as you made V-simplex; only you shall set before it the standard limb of I.
B make as the second V-simplex; but in the first upright omit the diagonal square at the top, and set upon the three original squares three others similar, but the seventh one you shall cut off diagonally from its lower hither angle.
Likewise when your B so made is turned upside down, then it will be a Q.
