A stunning map of North America that encompasses the Arctic all the way to the top most part of South America.  Senex’s map is derived from Guillaume de l’Isle’s maps of North America that were published between 1700 and 1703.  As such, it has been argued that his map “would have been among the first exposures of the British public to many of the new cartographic ideas about North America advocated by de l’Isle.”  These new cartographic ideas include the drawing of California as a peninsula, and a more detailed depiction of the Great Lakes region that included the claims made by Baron Lahontan and his influencial “River of the West”.
However, it should be noted that his drawing of California is incomplete and as such leaves the concept of a peninsula open for interpretation.
His inclusion of Lahontan’s claims however are important. Lahontan’s map was the first to draw the fictitious “Rivière Longue” emanating from the Great Lakes region and the Mississippi, as well as depicting the “Rivière Morte” that was claimed to have been drawn from reports by the Gnacsitares tribe.  This latter river system emanated from a Western mountain range, which we now know as the Rocky Mountains, and was linked to another river system on its Western side in the region of the “Pais des Mozeemlek”. Lahontan’s map was influential because it provided the possibility of an internal river route to the Pacific from the Great Lakes region.  Lahontan’s depictions of the “Rivière Longue” and the “Rivière Morte”, which eventually became known as the “River of the West” with its various fanciful drawings, were based on native claims that might be pure fabrications on the part of Lahontan.  As such, Senex tempers Lahontan’s claims by adding a note that states “unless the Baron Lahontan has invented these things, which is hard to resolve he being the only person that has travel’d into these vast countries.”
It is also of interest that Senex draws in some of the cities, such as Cibola, Quivira and Great Teguaio, associated with the so called “Seven Cities of Gold” myth of the American West.  This myth which has it beginnings during the age of the Spanish conquistadors led many to believe and thus search for these mythical cities and their claims to gold and wealth.
Also of interest is Senex's drawing of  Spanish wrecks in the Caribbean and the inclusion of Terra Incognita in the Arctic thus providing the viewer with a vast array of information relating to North America which remained, to a large extant, unexplored and fraught with wonder and danger.
This map is the second state dated 1710.
