[M.34L] [M.34]DiametersCircumferences of pillar: the one I have drawn of the two red ones,No 11. Ducal Palace. Upper arcade. 34 next St Marks. Bases. Fig 4 represents the leaf at i of fig 1 in profile, with Ft. in. its turn to the balustrade in perspective; the same turn At top of balustrade 4 " 11¾ being seen above at h - f: fig 1; observe that point f One foot above top of bal. 4 " 11 1/3 in fig 1 is f in fig 4; and Fig 3 is the section p2p in figs 2 --- --- --- --- --- 4 " 11 1 and 4. Now the section Fig 2 and section fig 3 One foot from top of shaft 4 " 10 coincide exactly from i to f: the flat space ip2 Fig 3, is At top, under band: 4 " 9½ the recession for baluster, and measures 2/3 of an inch: There height. is then a further recess, to the shaft of baluster p3-p4 in From base of shaft to top fig 1: and this also = 2/3 of an inch: and since the of abacus 11 " 1 outer side of the abacus of baluster coincide with p2 f From do: to below band 8 " 7¼ of fig 1: this p3 p4 represents the excess of the baluster From do to below roll 8 " 11¾ or 9 ft. abacus over its base. Returning to section fig 2 & 3 we see that in fig 3 a [diagram] Section of abacus on red shaft with Cornice, upper arcade. level space, e f is added at f: This gives a peculiar effect to the hollow of the great base; having the perfect a-b 1 5/6 in level e f instead of a swept curve: The curve gf and b c 1/3 level e f are wrongly divided in the measures of fig2: c d 5/8 in fig 3 g f round is 2½ inches exactly: substitting this d e 3½ for 2 1/8 in fig 2. it will give 1 5/8 instead of 2 in, for e g 1/3 e f: and the curve will be more accurately struck by this g f 1¼ division Another very peculiar character of this base is g h ½ At h springs out the diagonal flower. the rise b c of fig 2: marked from x in fig 4: its coincidence at a a2 or the excess of a from g 2 in exactly. with the line of plinth being point of turning: it is much flatter
