Barnhart concurs, stating that "the pictographs are in no way comparable to the figures found on the stone carvings or petroglyphs found in "Lenapehoking", the traditional homeland of the Lenape. David Oestreicher asserted that the stories were a conglomerate assembled from numerous sources from different cultures that spanned the globe. Barnhart was of the opinion that Rafinesque created the "Walam Olum" in hopes of winning the international "Prix Volney" contest hosted in Paris, and Barnhart thought that Rafinesque wanted to prove his long-held theories regarding the peopling of America. Oestreicher's findings were summarized by Herbert Kraft in his study, "The Lenape-Delaware Indian Heritage: 10,000 BCE to 2000 CE.", and by Jennifer M. Lehmann in "Social Theory as Politics in Knowledge".
