In 1704 CE a set of detailed architectural sketches were discovered in the drawer of an antique writing desk at an estate sale in Vienna. Sketched on washi kozo silk paper, they appear to show a remarkably detailed diagram of the Petra site in Jordan, with notes on its construction written in both French and Arabic. The papers were purchased by a private collector and later acquired by the British Museum, though their provenance has never been identified and they have not been publicly displayed in over a century.
