The appeal of animal portraiture is probably deeply linked to that of human portraiture. Yet the reasons underlying the appeal of both types of portraiture have received scant attention. The psychological appeal of human portraiture is poorly understood, and has also rarely been tackled by museum exhibits or art history. To understand the emotional appeal of animals in art, we probably ought to know what it is about human portraiture that we find so attractive, even spellbinding? Are we not accosted by 5, 50 or even 500 faces each day of our lives? Why does it matter on a given day if we see several more faces represented on canvas? It would seem that we measure the greatness of a portraitist in large part by the human emotion his art evokes. Why do we care? –Kobi
