century, were only known to the historian by the descriptions and allusions of the ancient authors. [5] Winckelmann's History of Ancient Art should be read in connection with his Remarks upon the History of Art, which is a kind of supplement to it, and takes the place of that new edition of which the author's premature and tragic death deprived the world. It is an answer to the objections which made themselves heard on every side; the preface to _Monumenti inediti_ (Rome, 1867, 2 vols. in folio, with 208 plates) should also be read. The method of Winckelmann is there most clearly explained. Finally, the student of the life and labours of Winckelmann may consult with profit the interesting work of Carl Iusti, _Winckelmann, sein Leben, seine Werke, und seine Zeitgenossen_, which will give him a clear idea of the state of archæology at the time when the German _savant_ intervened to place it upon a higher footing. In such a case as this the clearest and most precise of verbal descriptions is of less value than any fragment of marble upon which the hand of the artist is still to be traced. Who would then have guessed that the following generation would have the opportunity of studying those splendid groups of decorative sculpture whose close relation to the architecture of certain famous temples has taught us so much? Who in those days dreamt of looking at, still less of drawing, the statues in the pediments and sculptured friezes of the Parthenon, of the Thesæum, of the temples at Ægina, at Phigalia, or at Olympia? Now if Winckelmann was ignorant of these, the real monuments of classic perfection, it follows that he was hardly competent to recognise and define true archaism or to distinguish the works of sculpture which bore the marks of the deliberate, eclectic, and over-polished taste of the critical epochs. He made the same mistake in speaking of architecture. It was always, or nearly always, by the edifices of Rome and Italy, by their arrangement and decoration, that he pretended to explain and judge the architecture of Greece.
