But filmmaker Giesen now believes he's solved the mystery, maintaining that the line added to the score that reads "Wo Matthias die Saiten Streichelt" ("where Matthew plucks strings") is a reference to Mittenwald and its famous son Matthias Klotz, who founded the town's violinmaking tradition. Moreover, he contends that the score contains a schematic diagram of the train tracks that ran through Mittenwald in the 1940s, and that the rune and fragmented sentence "Enden der Tanz" ("end the dance") at the end of the score means the treasure can be found at the former site of the buffer stops.
The drilling effort in Mittenwald proved fruitful, unearthing a large quantity of unidentified metals. "Geologists call it an anomaly, a substance that doesn't belong there," says Giesen. He is now looking for a company specialized in excavations and dealing with explosives to continue the hunt, and is hoping to pay the costs by raising €25,000 with a crowdfunding campaign. He is also considering making a documentary about the project.
Local historian Jürgen Proske has his doubts about the find. "It could be a treasure chest," he says. "But it could just be a manhole cover."
