1650 - 1700 Map Intensive


November 11, 2017,

Will be workng on the Jolliet's Lost Map for a while... putting the piece together so that someone with knowledge of the maps of the 1670s associated with the names Marquette, Jolliet, Franquelin, Randin will see the commonality with the Lost Jolliet Map.

The JOLLIET MAP, specifically the Jolliet/Brown map, is not what is claimed for it.
It is not a legitimate historical document originating directly or indirectly from Jolliet.

1. The Jolliet/Brown Map is not Authentic,

The Jolliet Map Hoax

I was going thru my files last month and pulled out a map that I had filed away over ten years ago. I immediately knew that it was the Lost Map of Jolliet. I had back then photocoped it from an archive collection, unaware of its significance. But since then, my understanding of the maps of the period has improved considerably. This map has never been on the internet, nor has it ever been mentioned in its historical context.

But, in the course of putting together a paper on this, planning for an e-book, I happened across a discovery of equal, nay, greater importance to the history of the maps of the period: the discovery that the Jolliet/Brown map is a fake.

Evidence comming soon in pdf to update historians, and by educational osmosis, all cultureally aware educated people.

2. Jolliet Lost Map Identified,

This is in process. Clarifies identification, history and sequence for about ten maps relating to the 1672-78 period.

Image below, Jean Delanglez's article, 1946, on the Lost Map of the Mississippi. I have identified Delanglez' Lost Map. It is nothing like the one he theoretically reconstructed.
