Starna, and William Fenton published an article in the New York History journal entitled "The Tawagonshi Treaty of 1613: The Final Chapter." Their theory is that this written version is a forgery because it contains what they argue are grammatical anachronisms; that a blend of handwriting styles from the 17th and 20th centuries is used; that the names of villages and not chiefs are used; and that the writing is "too smooth" to be made by a 17th-century quill pen. Herkens writes that the document contains c. 40 grammatical anachronisms, and that on grammatical grounds it is likely that the text was written in the 20th century. Given that Van Loon forged other pieces from the same period, they point to him as the most probable forger. In 2013, linguistic experts Harrie Hermkens, Jan Noordegraaf, and Nicoline van der Sijs submitted the document to further linguistic and historical analysis, including its provenance and connection to Lawrence G. Van Loon. They also found the document to contain "a significant number of anachronisms making it impossible for the text to have originated in 1613. Nor is it possible that it is a later copy of a document since lost." Robert Venables, a retired Cornell University professor, is among those who remain convinced that the document version is also valid, and concurs with other scholars who point out that any inconsistencies in language and pen strokes can be explained by the fact that it was copied by hand years after 1613. The document was given to the Onondagas and remains near Syracuse, New York. 400th Anniversary Celebration In July and August 2013, hundreds of Native Americans and their allies took part in a river journey to recognize and renew the Two Row Wampum Treaty. Canoeing and kayaking across New York State, the participants called attention to the treaty and its significance for native land rights and environmental protection. The paddlers traveled from Onondaga, birthplace of the Haudenosaunee league, along the Mohawk and Hudson rivers to New York City, ending at a special session at the United Nations. The anniversary journey brought world attention to the Two Row Treaty. Organized by the Onondaga Nation and Neighbors of the Onondaga Nation (NOON), the renewal journey covered over 300 miles, with public events at sites including Kanatsiohareke Mohawk Community, Albany, Poughkeepsie, and Beacon NY, where Native leaders and public officials discussed the treaty and its bearing
