106 passed by this tomb and observed the basket with the tender young leaves growing round it. Delighted with the novel style and form, he built some columns after that pattern for the Cor­inthians, determined their symmetrical proportions, and estab­lished from that time forth the rules to be followed in finished works of the Corinthian order.

11. The proportions of this capital should be fixed as follows. Let the height of the capital, including its abacus, be equivalent to the thickness of the base of a column. Let the breadth of the abacus be proportioned so that diagonals drawn from one corner of it to the other shall be twice the height of the capitals, which will give the proper breadth to each face of the abacus. The faces should curve inwards, by one ninth of the breadth of the face, from the outside edge of the corners of the abacus. At the bottom the capital should be of the thickness of the top of the column omitting the congé and astragal. The height of the abacus is one seventh of the height of the capital.

12. Omitting the height of the abacus, let the rest be divided into three parts, of which one should be given to the lowest leaf. Let the second leaf occupy the middle part of the height. Of the same height should be the stalks, out of which grow leaves pro­jected so as to support the volutes which proceed from the stalks, and run out to the utmost corners of the abacus; the smaller spirals between them should be carved just under the flower which is on the abacus. The flowers on the four sides are to be made as large as the height of the abacus. On these principles of proportion, Corinthian capitals will be finished as they ought to be.

There are other kinds of capitals set upon these same columns and called by various names, but they have no peculiarities of proportion of which we can speak, nor can we recognize from them another order of columns. Even their very names are, as we can see, derived with some changes from the Corinthian, the cushion-shaped, and the Doric, whose symmetrical proportions have been thus transferred to delicate sculptures of novel form.
