The desire for decoration is probably as old as the human race. Nature, of course, is the source of beauty, and this natural beauty affects something within us which has or is the faculty of reproducing the cause of its emotion in a material form.

In a mild or elementary form, probably both casts of faculty exist in every animated creature, and especially in the human being.
