§ XIII. Now, the reader is to remember, there is nothing magical in salvia leaves: the line I take from them happened merely to fall conveniently on the page, and might as well have been taken from anything else; it is simply its character of gradated curvature which fits it for our use. On Plate XI., opposite, I have given plans of the spurs and quadrants of twelve Italian and three Northern bases; these latter (13), from Bourges, (14) from Lyons, (15) from Rouen, are given merely to show the Northern disposition to break up bounding lines, and lose breadth in picturesqueness. These Northern bases look the prettiest in this plate, because this variation of the outline is nearly all the ornament they have, being cut very rudely; but the Italian bases above them are merely prepared by their simple outlines for far richer decoration at the next step, as we shall see presently. The Northern bases are to be noted also for another grand error: the projection of the roll beyond the square plinth, of which the corner is seen, in various degrees of advancement, in the three examples. 13 is the base whose profile is No. 26 in Plate X.; 14 is 24 in the same plate; and 15 is 28.
[Illustration: Plate XI. PLANS OF BASES.]
§ XIV. The Italian bases are the following; all, except 7 and 10, being Venetian: 1 and 2, upper colonnade, St. Mark's; 3, Ca' Falier; 4, lower colonnade, and 5, transept, St. Mark's; 6, from the Church of St. John and Paul; 7, from the tomb near St. Anastasia, Verona, described above (p. 142); 8 and 9, Fon daco de' Turchi, Venice; 10, tomb of Can Mastino della Scala, Verona; 11, San Stefano, Venice; 12, Ducal Palace, Venice, upper colonnade. The Nos. 3, 8, 9, 11 are the bases whose profiles are respectively Nos. 18, 11, 13, and 20 in Plate X. The flat surfaces of the basic plinths are here shaded; and in the lower corner of the square occupied by each quadrant is put, also shaded, the central profile of each spur, from its root at the roll of the base to its point; those of Nos. 1 and 2 being conjectural, for their spurs were so rude and ugly, that I took no note of their profiles; but they would probably be as here given. As these bases, though here, for the sake of comparison, reduced within squares of equal size, in reality belong to shafts of very different size, 9 being some six or seven inches in diameter, and 6, three or four feet, the proportionate size of the roll varies accordingly, being largest, as in 9, where the base is smallest, and in 6 and 12 the leaf profile is given on a larger scale than the plan, or its character could not have been exhibited.
