Note 5 — PART VI.
Charles Lock Eastlake translation
Vasari observes, "L'unione nella pittura è una discordanza dicolori diversi accordati insième."—Vol. i. c. 18. This observation is repeated by various writers on art in nearly the same words, and at last appears in Sandrart: "Concordia, potissimum picturæ decus, in discordiâ consistit, et quasi litigio colorum."—P. i. c. 5. The source, perhaps, is Aristotle: he observes, "We are delighted with harmony, because it is the union of contrary principles having a ratio to each other."—Problem.
