In February 2012, the Vatican's Secret Archives will show a 100 of its prized documents. Among them, is the original parchment that holds the dogma of the Immaculate Conception. It's titled the 'Bolla Ineffabilis Deus.' It dates back to 1854 and it's signed by Pius IX.
Also on display will be a letter St. Marie Bernadette Soubirous sent to pope Pius IX in 1876. It deals with the apparitions of the Virgin of Lourdes, which is one of the few appearances recognized by the Vatican. The letter is hand-written in French, by the very Bernadette Soubirous.
