The Red Bird River Shelter Petroglyphs are a series of petroglyphs, or carvings, on a stone in Manchester, Kentucky, USA. The petroglyphs have been interpreted as inscriptions in at least 8 Old World alphabets, all of which were extinct when Columbus arrived in the New World in 1492. The rock was enrolled on the National Register of Historic Places in September 1989.
On December 7, 1994, the 50 ton stone stone fell from a sandstone cliff above the Red Bird River, and rolled onto Highway 66 at Lower Red Bird. On December 9, 1994, it was transported to its present location, where it is roofed over and fenced. The alphabets apparently inscribed on the stone include 1st century Greek and Hebrew, as well as Old Libyan, Old Arabic and Iberian-Punic which probably dates from the 9th century BC. Ogam, Germanic Runes, and Tiffinag-Numidian inscriptions have also been identified. Some speculate it's authenticity.
