In 1981, archaeologist Robert L. Pyle of Morgantown, West Virginia began exploring the mountains of the southern part of the state studying petroglyphs (markings on stone) that at first glance resembled archaic runes and were different from traditional ancient American rock carvings. His archaeological research focused on petroglyph sites in Wyoming County, West Virginia, and Manchester, Kentucky.
Research indicated the markings were an ancient alphabet known as Ogam (or Ogham), found in the British Isles, especially Ireland, Scotland, and Wales. (The petroglyphs in West Virginia and Kentucky exhibit what is known in Europe as stem type Ogam.) The markings were considered in connection with the tradition of St. Brendans voyages to this continent in the 6th century.
These are not the only Old Norse or Latin carved petroglyphs on the North American continent of the CE time period. But, this petroglyph is heralded by some as the Rosetta stone of Old Norse and Latin as the same message is written in both symbologies.
Dr. William Grant, Edinburgh University, Scotland, and Dr. John Grant, Oakland, Maryland, both Celtic linguists/scholars, participated in Pyles Ogam research in southern West Virginia and endorsed the West Virginia petroglyphs as authentic archaic Ogam. The Grants were former students at the Catholic University in Washington, DC, under the direction of Dr. Robert Meyer, Celtic professor and linguist for 33 years.
