Horses always seem utterly inscrutable. Even when they laugh or weep, they look quite imperturbable. All the horse’s powers of expression have gone into its parts: these are never still for a minute, twitching, twirling and signaling in various directions. It’s a real pleasure to look at them: such mobility against the background of a dolefully-despondent, somewhat disapproving muzzle. The horse’s soul—sensitive and finely tuned—is wholly in its ears.
–Abram Tertz, A Voice from the Chorus, 252
