The Crown with its little Cymatium must have the same height with the Face of the middle of the Architrave.
The great Cymatium ought to have the height of an 8th. part more than the Crown or Drip.
The Jetting or Projecture of the whole Cornice comprehending the Dentil ought to be equal to the space that there is from the Frise, just to the top of the great Cymatium, and generally speaking all the Jettings or Projectures shall have the better grace when they are equal to the height of the Jetting Members. See Table [VII.]
ART. VIII.
Of the Corinthian Order.
HE Pillars of the Corinthian Order have no other Proportions than the Ionick, except in the Capital, whose height make them appear slenderer and higher. The other parts or Members, as the Architrave, Frise, and Cornice, borrow their Proportions Lib. 4.
Chap. 2. from the Dorick and Ionick Order, having nothing particular, for the Corinthian Modillons are imitated by the Mutils of the Dorick Order, and the Dentils are the same with the Ionick; this being so, we have nothing to do but to give the Proportions of the Capital, which are these; The Capital comprizing the Abacus, hath for its height, the breadth of the bottom of the Pillar.
To have the true breadth of the Abacus, we must have a care that its Diagonal be double the height of the Capital, the bending that the sides of the Abacus have inward, is a 9th. part of a side, the bottom of the Capital is equal to the Neck of the Pillar. The thickness of the Abacus is a 7th. part of the whole Capital.
Two of these seven parts must be taken for the height of every Leaf, of which there are two Ranks, each of which has four Leaves.
