Certain artistic details, as the lightnings shooting in various directions from a central point (as from the hand of Jove), were also unknown to the art notions of the red race. The treatment of the sun as a face, with rays shooting from it, I also consider foreign to the pictography of the Delaware Indians, nor have I yet seen any specimens proved to be of their manufacture that present it. It is found, indeed, in Chippeway pictography, but there only in late examples.Several other scholars were of a similar feeling, that the Lenape Stone was hoaxed. Some have noted that the stone was broken, and that the mammoth carving does not align properly when the halves are joined.
The execution of such imitations also usually betrays their origin. The lines on the Lenape Stone are obviously cut with a metal instrument, making clean incisions, deepest in the centre and tapering to points-quite different from the scratch of a flint point. Shrewder fabricators than the unknown author of this one make use of flint points. Some of the Western 'tablets' have been so inscribed. They may thus conceal their tools, but there are other resources for the archaeologist. The surface of all stones undergoes a certain chemical change on exposure to the air, which is called by the French term patine. In many varieties, as flints, jasper, and hard shales, this affords a decisive means of discriminating a modern from an ancient inscription or arrow-head. It requires the use of the microscope and some practice, but with these most of such impostures can be detected.
The Lenape Stone is currently housed in the Mercer Museum in Doylestown.
