            Propositions in a Landscape 
 There is a genre in the illustration of books where scientific propositions 
        are explained diagramatically but also set within a recognisable landscape. 
        The fusion doesn't have to be between realism and the geometric.
 The convention of the Diagrammatic precariously joined the 
            the topographic. Compare the Le Clerc and the Cleland to see how
  extensive is the influence of the medium. Note the dates.
 In cartography,
      there is often a combination of the Illusionistic and the Diagrammatic.  02 J.W.Goethe, Farbenlehre , published in Tübingen in 1810.
      This is the much reproduced hand coloured engraving found in the great German
      poet and theoretician's central work on the properties of colour.

          most interesting way.  04 from G.B.Agricola, De Mensuris & Ponderibus Romanorum Atque Graecorum ,published
