Quum pagina non caperet integrum stylobatam tantæ molis, fingere oportuit detractum illi esse aliquid de trunco; ac partem supremam stylobatæ sustentari ab infima, non immediatè, sed per quatuor asseres; eisque impositam fuisse adjumento funium suspensorum ex trochlea. Elevatio geometrica stylobatæ est B; vestigium geometricum est A. Ex his eruitur optica delineatio vestigii C & elevationis D. Ac postea formatur stylobata nitidus E, accipiendo latitudines ex vestigio C, altitudines ex elevatione D.
The Thirteenth Figure.
The Projection of a Pedestal, of the Composite Order, in Perspective.
Wanting Room in this Page to describe so large a Pedestal entire, we imagine it to have lost part of its Trunk, and the upper part to be set on the lower; not immediately, but on four Cross-pieces that intervene; and for placing it thereon, we suppose the Assistance of Ropes and a Pulley. The Geometrical Elevation of the Pedestal is B; its Plan A; from whence are found their Projections in Perspective D and C. Then taking the Breadths from the Plan C, and the Height from the Elevation D, you complete the finish’d Pedestal E.
