The EXPLANATION of

Plate

T HIS opiate contains all that has been explain d in the fit ft (partwhich treats of the (Proportions common to all the Orders, as wellivhat appertains to their Heights, as to their (Breadths and ProjeBures ;the Heists being determind by entire Modules, and the ProjeBures by the"Division of the Module into she : supposing, as has been said, that thethe Module is the Third of the Diameter of the Bottom of the Column, whichI call the little Module.

It appears by this Plate, that all the Entablatures have fix little Modulesin Height, which makes two Diameters of the Bottom of the Column. Thatthe Length of the Column goes increasing, from Order to Order, by an equalProgrefion of two Modules, the Tuscan having twenty-two, the Dorictwenty-four, the Ionic twenty-ftx, the Corinthian twenty-eight, and theComposite thirty Modules. That all the Pedeftals go likewise increaftng ibut only by one Module 3 the Tuscan having fix, the Doric seven, theIonic eight, the Corinhtian nine, and the Composite ten. That eachPedestal divided into four Parts, has one for its whole Base, and the Halfof one for its Cornice. That the whole Base being divided into three Parts,one is given to the Mouldings, and the two others to the Zocolo. Andlastly, that the ProjeBure of the Base is equal to the Height of the Mould-ings of the fame Base.

This Plate also shews, that the other ProjeBures are determin d byFifths of the little Module, the ProjeBure, which the Shaft of the Columnhas below, beyond what it has above, which is call’d the Diminution, beingdetermind by one of these Fifths, which is the Space from A to B 5 theProjeBure of the CinBure or Fillet, which is at the Bottom of the Shaft ofthe Column, by another Fifth, which is the Space from B to C 5 that of theupper Torus, and of the Fillet below the Scotia, by another Fifth, which isthe Space from C to D, and the ProjeBure of the whole Base, by thePart which is from D to E, supposing that each of these Fifths containsfour Minutes, of which, the Diameter, at the Bottom of the Column, con-tains sixty, the mean Module thirty, and the little Module twenty.
