“What I see in these paintings is the way Nixon sees the vastness of the landscape.  He sees it oddly by invoking its sound - by evoking actually a sort of serenity, the tranquility of the open field,  something not typically associated with paintings.  But Nixon’s are quiet and you must be very still to see them.  No breeze stirs; no figure breaks the sound of that near-silent stillness of the endless meadows and vaulted skies.”
