Origin here means that from and by which something is what it is and as it is. What something is, as it is, we call its essence or nature. The origin of something is the source of its nature. The question concerning the origin of the work of art asks about the source of its nature. On the usual view, the work arises out of and by means of the activity of the artist. But by what and whence is the artist what he is? By the work; for to say that the work does credit to the master means that it is the work that first lets the artist emerge as a master of his art. The artist is the origin of the work. The work is the origin of the artist. Neither is without the other. Nevertheless, neither is the sole support of the other. In themselves and in their interrelations artist and work areeach of them by virtue of a third thing which is prior to both, namely that which also gives artist and work of art their names – art.
