The Brandenburg stone is an inscribed stone slab found in Brandenburg, Kentucky, United States in 1912, on the farm of Craig Crecelius. The stone contains a strip of linear markings that resemble letters of a script. Crecelius exhibited the stone several times, but was unable to find anyone who could identify the markings.
Jon Whitfield, who acquired the stone in 1965, claims that they are Coelbren, a fake Welsh-language alphabet invented around 1791.[1] Other writers have elaborated on these claims, arguing that this is evidence of pre-Columbian contact between the legendary Welsh prince Madoc and Native Americans. The consensus of Welsh scholars is that "Coelbren" is a fake script invented in the late eighteenth century by a literary forger, Iolo Morganwg, in his book Barddas.[1]
