The grandsire never took it; the _naked_ Pict never had it. And yet the directors of this Crystal Palace have taken Mr Owen Jones’s word for it. They have inconsiderately, and with the worst taste, delivered up the Palace into Mr Jones’s hands. We dread his being put into any other palace, for he evidently longs to be stuccoing and daubing the real marbles. “The experiment cannot be fairly tried, till tried on marble”—and he looks to a wide area, ample verge, and room enough, “and in conditions of space, atmosphere, &c., similar to those under which the originals were placed.” We however owe it to Mr Owen Jones’s candour in admitting a note by Mr Penrose, which vindicates the character of this odious marble. Thus speaks Mr Penrose: “An extensive and careful examination of the Pentelic Quarries, by the orders of King Otho, has shown that large blocks, such as were used at Athens, are very rare indeed. The distance, also, from the city is considerable: whereas there are quarries on Mount Hymettus at little more than one-third the distance (and most convenient for carriage), which furnish immense masses of dove-coloured marble, much prized, it would seem, by the Romans (Hor., ii. 18), and inferior in no respect but that of colour to the Pentelic. It could, therefore, only have been the intrinsic beauty of the latter material that led to its employment by so practical a people as the Athenians.” It will occur to the reader to ask if there is not here something like a proof that they did not intend this Pentelic marble to be painted; for it is manifest, under the stucco-and-painting theory, the dove-coloured of Hymettus would have answered all purposes. But Mr Owen Jones triumphs over his own candour. He sees nothing in the admission of this note of Mr Penrose; he takes it up, he exhibits it, merely for the purpose of throwing it down and trampling upon it. He gives it a scornful reply.—_Reply_ in large letters. It is a curious one, for, like the boomerang, it flies back upon himself, and gives his own arguments a palpable hit. The reader may remember how he had asserted that “the Athenians built with marble because they found it almost beneath their feet.” In his oblivious reply, he discovers that the Athenians used it because it was a great way off from their feet; nay, that the worst part of the matter was, that it was no farther off from their feet. He uprises in reverential dignity, to reprove “our present ideas of economy.” “I do not think that, with our present ideas of economy, we are able to appreciate the motives of the Athenians in choosing their marble from the Pentelic quarries, in preference to those of Mount Hymettus. We must remember that the Greeks built for their gods; and the Pentelic marble, by presenting greater difficulties in its acquisition, may have been a more precious offering.” Mr Jones thus offers two contradictory motives on behalf of the Athenians—_one_ must be given up.
