Unfortunately not, the seriousness of the error was not noticed until the 1930s, although even in the 1870s it was clear he got the wrong layer. Sir Arthur Evans actually was partially inspired to excavate at Knossos out of the fear some other similar amateur might destroy the sight, and while there's a lot to critique about Evans, he was a pretty good excavator for the time (and also surprisingly anti-imperialist for someone who ended up with half of Crete in his museum, he played a strong role in halting a massacre of the local Muslim population and was harshly critical or British-Turkish actions in Crete.)
