Considering normal maps that geographers do, it is possible to discuss strange maps in confrontation with the status of real maps. It is by using a precise epistemological model inspired by S. Lupasco that we will examine four relevant examples of fictuous maps. We will refer explicitly to a ternary epistemological model to confront extravagant situations furnished by litterature in regard to our normal maps. By using an explicite ternary language in relation here to the structure of the map, we will refer to the two fundamental concepts of scale and legend to show how those four fictions are emblematic and help us to understand the real maps. The ternary model scale/legend/mapmaking will be the reference model to illustrate how the Captain's map in L. Carroll, the Utopia Island of T. More, the Map of China of J.-L. Borgès and the Tender Map of M. de Scudéry are referenced in our model in regard of the real map, tertium datur, the mediator in the interaction of scale and legend.
