PN: There is no horizon in oblique projection - no beyond.
MS: Between sea and sky, is the line of the horizon. The oblique projection of the drawings of Nobson does not include a horizon to their infinite plain, and so the sun, above the horizon, is absent. But there are works that deal with the horizon.
Sea V for example is sea and sky as converging tone, and treated almost digitally in the repeated modular units of sky and beach within which we might read something in the sand. The horizon becomes threshold of discontinuity of understanding, rather than about distance.
PN: The Other.
