This infography is litteraly a "map of maps" : it shows, under the form of a phylogenetic tree, the relation between Middle-earth maps and cartographers.As in a Sankey diagram, the branch thickness is proportional to the importance of the map.I retained only influential or interesting maps, on my point of view (limited and subjective). I apologize for the cartographers I forgotten.This infography was created at the same time as the writing of an essay about cartographers of Middle-Earth :The frames concerning J.R.R. Tolkien and Chr. Tolkien are based on the list of maps published by the french website Tolkiendil :John Howe produced 4 "official" maps.
