A man in England weeding his garden has made a once-in-a-lifetime discovery: a stone inscribed with a 1,600-year-old message in a rare Irish alphabet.
At first glance, the inscription looks like a series of vertical lines cut into the chocolate-bar-size stone. But these lines are actually an inscription in ogham, an alphabet used to write the early Irish language after the fourth century and Old Irish from the sixth to the ninth centuries. Its discovery has baffled archaeologists, who can't explain how it came to be in the central English city of Coventry.
