Part II. five Kinds of Columns. 1 21
to put them in those Places where there can be neither Rafters norPurlins. The Custom of making Triglyphs in any other Part thanover the Columns, which is the only Place where there are Beams,whose Ends the Triglyphs represent, may also be put in the num-ber of those licentious Practices which Custom has authoris’d.
But there are other Abuses which have no more Authority thanwhat is barely sufficient to make them tolerable, and which oughtat least, to be avoided, for greater Perfection 5 supposing they arenot absolutely to be condemn d. Palladio has made a Chapter ofthem, and reduces them to four only, which are the placing Car-touches to bear any thing 3 the breaking of Pediments, and leavingthem open in the middle 3 the affecting a great Projecture for Cor-nices, and the making Columns with Rusticks^ but I think othersmay also be added, some of which, possibly, might not be intro-duced in the Time of Talladio : For besides those which I have spo-ken os, in the precedent Chapter, which respect the Change of Pro-portions' I take notice of several others, the greatest part of which,indeed, are not so bad, as those mention'd by Valladio.
The first is the making Columns, and Pilasters, interfere, andpenetrate each other. This Penetration, in Columns, is more rarethan in Pilasters. There is an Instance in the Court of the LouWe ,where, in the inward Angles, as A, there are placed two Columns,
B C, instead of being content with the Column D, which is capa-ble of doing as much as the two Columns B and C, and muchmore naturally, if I may so fay, supposing, that as the Column E.sustains the two Architraves which make the prominent Angle* theColumn D bears also those which make the inward Angle 3 therebeing no Reason why one Column should not be sufficient to bearthe inward Angle, since it is so, for bearing the outward one.

Talladio, in a Palace which he built at Vicen^a, for the Count Vale*rio Cbiericato , has also made Columns which penetrate each other,which he calls double Columns.
