This is one of the most brutal takedowns I have ever read in art criticism. It is one thing to be rebuked or contradicted; it is another thing to be dismissed as not worth the time:

“Claude and the Poussins were weak men, and have had no serious influence on the general mind. There is little harm in their works being purchased at high prices: their real influence is very slight, and they may be left without grave indignation to their poor mission of furnishing drawing-rooms and assisting stranded conversation”
