An alchemical book, published in Paris in 1613 as Livre des figures hiéroglypiques and in London in 1624 as Exposition of the Hieroglyphical Figures was attributed to Flamel.
It is a collection of designs purportedly commissioned by Flamel for a tympanum at the Cimetière des Innocents in Paris, long disappeared at the time the work was published. In the publisher's introduction Flamel's search for the philosopher's stone was described. According to that introduction, Flamel had made it his life's work to understand the text of a mysterious 21-page book he had purchased.
The introduction claims that, around 1378, he travelled to Spain for assistance with translation. On the way back, he reported that he met a sage, who identified Flamel's book as being a copy of the original Book of Abramelin the Mage. With this knowledge, over the next few years, Flamel and his wife allegedly decoded enough of the book to successfully replicate its recipe for the Philosopher's Stone, producing first silver in 1382, and then gold.
