1650 - 1700 Map Intensive

 

The image below, Figure 20 from Weber's Invalidating the Jacques Marquette Map, is a three map contrast. It is motivated to help throw light on whether or not the Jesuit Map was based on the Marquette Map. If the middle map, below, was based on the left side map, and the middle map was sent to France in 1675, then the dating of the left side map is more certain from 1673-74, and not a 19th century fake. The right map was the first to have the Mississippi red-section contour. The middle map took the contour from the right side map, dating the middle map to at least 1703, the middle map not serving as a template for the right side map in 1675.

 

As more detailed in Weber's affidavit, the following is a summary of the plagiarism published in the Journal of Illinois History.

What is also overlooked by the fact-checkers at this academic journal is that the facts of the plagiarized material are themselves erroneous (!). The intent of the surreptitious appropriation was to use the itself-erroneous "argument" to prove that the Marquette Map, that suddenly appeared to history in 1844, was authentically the map made by Marquette in 1673-74. In fact, the more likely characterization is that it is the most substantial fraud in the history of the cartography of North America.

In summary, Buisseret, Kupfer and Campeau believe: 1.) Marquette Map served as a model for the Jesuit Map. 2.) The Marquette Map was in Quebec in 1675. 3.) The Jesuit Map was sent to France by 1676.

 

1.) Marquette Map "served as the model for" the Jesuit Map

Campeau, p. 66

Marquette's map served to create the present one ... The latitudes of the Jesuit discoverer are also respected. It is therefore certain that Marquette's Map served as the model for this one.

Buisseret and Kupfer, p. 271

The surest indication that the map relied on the Marquette Map are...

2.) Marquette Map was in Quebec in 1675

Campeau, p. 66

As this is the most evident proof of the influence of Marquette, allowing us to date this map [Jesuit Map] to 1675.

Buisseret and Kupfer, p. 274

...someone in Quebec had access to the Marquette Map and other material and sent the information back to Paris, probably in 1676.

3.) Jesuit Map sent to France by 1676

Campeau, p. 67

I have no doubt that here we have a work [the JESUIT MAP] by the Jesuits, who were quick to communicate to France the information given by the papers of Marquette.

Buisseret and Kupfer, p. 274

...someone in Quebec had access to the Marquette Map and other material and sent the information back to Paris, probably in 1676.
