Este é considerado o primeiro mapa de Edgar Rice Burroughs 'de Barsoom . Desde que este mapa foi criado, houve várias tentativas de mapear Barsoom de vários escritores e editores contando histórias sobre Barsoom.
Edgar Rice Burroughs drew crude maps to locate his John Carter's adventures, but he was not a cartographer. Moreover, his work constitutes entirely a second hand account. He was not the source, rather, he related tales told by John Carter. Accordingly, as a dedicated and prolific scribe, he may be forgiven for the occasional error.
In the 1940's a substantially more elaborate map was drafted, intended to overlay ERB's Barsoom over the map of Mars as it was known then. That original Map of Mars has turned out to be highly inaccurate, and so the superimposition of Barsoomian locations must be taken as equally inaccurate. In fact, the most compelling thing about the 1940's map is that it was an attempt, and it was clearly ERB’s intention to superimpose Barsoom onto Martian geography. ~ Den Valdron from the Geographers of Mars Series
Desde este primeiro mapa, muitos mapas mais fantasiosos foram desenhados e criados e, embora o mapeamento original de Marte para Barsoom seja considerado um fracasso, ele não impediu que os escritores criassem novos mapas e imaginassem novos contos no livro de Burrough. Barsoom.
