The world of Irish folk dancing has been thrown into turmoil following the discovery of an ancient text.
The discovery was made by historian Declan O'Handcream while carrying out research at Trinity College, Dublin.
Searching through some ancient books in a rarely-visited section of the college library, he came a across a dusty old tome which looked like it hadn't been opened in years.
Imagine his surprise when, on blowing away the dust and cobwebs, he saw the title: "The Irish Dance, Part Two: The Arms."
"Well, you could have knocked me down with a feather for sure," said Dr O'Handcream. "As a historian, you always hope to discover an unknown text that will throw light on some aspect of history.
"But to find something as culturally significant as this is amazing!"
Irish dance experts are now examing the 500-odd page book, which is beautifully illuminated in bright coloured inks and gold leaf.
Dance critic and historian, Neville "Leapy" Points, said: "This is very exciting and offers a great opportunity for the likes of Michael Flatley to reinvent their shows.
"We can all enjoy Riverdance all over again - with arms! How wonderful, love!"
