Fake Gospel of St. Mark

The manuscript, written in Greek, originally was believed to have been written as early as the 14th century. But strong suspicions that it might not be nearly so old surfaced in 1989, after it was discovered that a blue pigment on one of the pages wasn't available until 1704, Mitchell said.
It took carbon dating, advanced microscope technology and good sleuthing to discover the faker's crafty handiwork.
Through analysis of parchment, ink and paints used in the book, Joseph Barabe, a senior research microscopist at Westmont-based McCrone Associates, determined the book was created after 1874 using materials not available until the late 19th Century.
