A New Treatise of the TUSCAN ORDER. CHAP. I.
THE first Column, which is the Tuscan, is like unto a gross man, strong and well set, therefore it is call'd the Rustick Work. The height of this Column, with the Pedestal, Architrave, Friese, and Cornish, is divided into nine parts, whereof two shall be for the Pedestal: These two parts divided in six, one shall be for the Basis, the other for the Cornish. The four parts remaining, are to be drawn into a square, which are to be divided by two Diagonal lines; within this square, set a Circle be made, and within that Circle let another square likewise be made; and within this, let a Circle be made which shall be the thickness of the body of the Column below noted A; but the out∣most square shall be the breadth of the Plinth of the Basis, noted B. The thickness of the body above, shall be the square which is in the middle, to be divided into eight parts; whereof two shall be the di∣minishing of the body of the Column. The Projecture of the Cimatum of the Plinth, noted C, shall be divided into six parts; whereof one must projecture where the square must be, as you shall see it marked with a Cross on the right side. The Basis, on the left side, noted D, must be divided in two parts, one shall be the Plinth: the other divided into four, the one shall be the Fillet above the Basis; another of the said four parts divided into two, one maketh the lower Fillet, which must project into the square, as may be seen in the great Pedestal following. And by this the whole Projecture shall be the seventh part of the Pedestal. The Cornish of the Pedest••l on the left side, noted E, is divided in∣to four parts, whereof one is to be given to Cima, two to the Plinth, the fourth to the Astragal. The Base of the Column noted F, is to be set upon the Pedestal, at half the thickness of the Column, di∣vided in two parts, whereof one shall be the Plinth; the other divided into three parts, whereof two are for the Thorus, and the part remaining for the Fillet: The Projecture is as much as from the outward square unto the inward square; the Fillet must project one square beyond the Column, and the remainder must be for the Thorus. The height of the body of the Column noted G, is of six parts of its diameter with its Base and Capital. The Capital noted H, shall be as high as half the body of the Column below, and is divided into three parts, whereof one part is to be for the Abacus of the Capital, another for the Boultin; the part remaining for the Neck, the Egs and Achors, being di∣vided into four parts, one part shall make the Fillet, the rest make the Egs and Anchors. The Neck noted I, is divided in two parts, which is marked with two little Crosses, the one is the breadth of the Astragale; this Astragale again divide into three parts, whereof one shall be for the Fillet, the eighth part of the thickness of the body of the Column below, shall be the Projecture of the Capital: the Astragale must project in a square; as may be seen more plainly in the great Capital following the projecting of the body of the Column noted K; is made after this manner, The said Column in its length, between the Base of the Column and the Astragale, it shall be divided into six parts, where∣of two shall remain below, and is the third part of the height; having made a division from the bot∣tom to the top, you shall draw lines passing through on each side; and upon the line of the third part, you shall set a Compass compassing from one end to the other; apply the Compass to the side, and divide the Circle from one of the sides of its half Circle, unto the place where the Perpendicular line falleth off the Scapus or thickness of the Column above, until it be on the sixth part of Icnographia, being on the Pedestal, where they divide the round of the side into four parts, which you shall make with lines across, as it appeareth in this Figure. Likewise you shall draw out of each part, a line pro∣ceeding upward, beginning on the outside, and reaching unto the sixth part of the body of the Column, and so following the second and third of the lines so drawn, each in his place; let the lines of the di∣minishing be drawn, proceeding across unto the other, and by this the body shall have its diminish∣ing: and to render it more equal and pleasant to the eye, whereas the Circle is divided into four parts, divide the same space into 5, 6, 7 or 8, and the body of the Column likewise; for the more divisions you make thereof, the said diminishing will be the more equal and pleasing; but I would not make it into more then four; for to make the manner thereof more intelligible to those that have less skil in this Art, the which having practised in four divisions, will make the other more easie to them.
There is yet another manner of diminishing of Columns, which Vitruvius sets forth in his third Book, Chap. 2. which is made after this manner; it is, That each of those Columns which shall reach from the Basis unto the Capital, about fifteen foot of height, the Diameter of this Column below, ought to be divided into six parts; and of this it will suffice that the end above have five of them: Of those which shall be from fifteen to twenty foot, the greater end below shall be divided into six parts and a half, whereof you must allow five and an half for the end above: of another, which may have from twenty to thirty feet, let the Diameter below be divided into seven parts and an half, whereof there
