Dighton Rock

Dighton Rock is America's oldest cold case — a forty-ton boulder in the Taunton River covered with petroglyphs that nobody has ever convincingly read. John Danforth drew its carvings in 1680 and sent the sketch to Cotton Mather, who published it as a mystery; since then, more than six hundred books and articles have attributed the marks to Phoenicians, Vikings, Egyptians, the Lost Tribes, a lost Portuguese explorer, and a prince from Atlantis. The one attribution that was rarely considered — by the colonists who first wrote about it — was the obvious one: the Indigenous people who had always lived beside the river.

The rock sat in the tidal water until 1963, when dam construction lifted it to a landfill promontory and eventually a museum shelter in Dighton Rock State Park. The carvings themselves are almost certainly Native — scholars now read the glyphs as consistent with regional petroglyph traditions — but the three centuries of misattribution are the artifact's real history: a record of how badly colonial and early American writers needed the marks to belong to anyone but the people still living there.

The file keeps Dighton Rock: the 1680 drawing, the six hundred theories, the Viking and Portuguese claims, and the slow scholarly correction that returned the glyphs to their makers.

Dighton Rock is the archive's misattribution file — the petroglyphs, the centuries of theories, and the argument about who gets to make marks in America.
