"It is a common failing among practitioners of art to become accustomed to a way of coloring, as if things were bound to their manner, and not their manner bound to the nature of things. Many, however, because of a certain natural inclination, adopted manners of coloring that seemed ideally suited to that branch of art to which they were most inclined. And so Hercules Segers concerned himself with savage mountains: and one [another artist:] Liefrinck painted imaginative rocks. Gemstones are also wonderfully colored, and the attractions of shells and other treasures from the sea have their particular admirers."
