IV. DISTRIBUTION.--And now, lastly, we come to the fourth great head of our inquiry, the question of the wise distribution of the art we have gathered and preserved. It must be evident to us, at a moment's thought, that the way in which works of art are on the whole most useful to the nation to which they belong, must be by their collection in public galleries, supposing those galleries properly managed. But there is one disadvantage attached necessarily to gallery exhibition, namely, the extent of mischief which may be done by one foolish curator. As long as the pictures which form the national wealth are disposed in private collections, the chance is always that the people who buy them will be just the people who are fond of them; and that the sense of exchangeable value in the commodity they possess, will induce them, even if they do not esteem it themselves, to take such care of it as will preserve its value undiminished. At all events, so long as works of art are scattered through the nation, no universal destruction of them is possible; a certain average only are lost by accidents from time to time. But when they are once collected in a large public gallery, if the appointment of curator becomes in any way a matter of formality, or the post is so lucrative as to be disputed by place-hunters, let but one foolish or careless person get possession of it, and perhaps you may have all your fine pictures repainted, and the national property destroyed, in a month. That is actually the case at this moment, in several great foreign galleries. They are the places of execution of pictures: over their doors you only want the Dantesque inscription, "Lasciate ogni speranza, voi che entrate." Supposing, however, this danger properly guarded against, as it would be always by a nation which either knew the value, or understood the meaning, of painting,[13] arrangement in a public gallery is the safest, as well as the most serviceable, method of exhibiting pictures; and it is the only mode in which their historical value can be brought out, and their historical meaning made clear. But great good is also to be done by encouraging the private possession of pictures; partly as a means of study (much more being always discovered in any work of art by a person who has it perpetually near him than by one who only sees it from time to time), and also as a means of refining the habits and touching the hearts of the masses of the nation in their domestic life. [13] It would be a great point gained towards the preservation of pictures if it were made a rule that at every operation they underwent, the exact spots in which they have been re-painted should be recorded in writing.
