Eric Cline, the author of the piece, wrote the book "1177 B.C.: The Year Civilization Collapsed", a book on the bronze age collapse I found very interesting. In the 1980's, the BBC produced a series called "In Search of Troy", written and presented by Michael Wood, the historian. Cline brings this up to date with Manfred Korfmann's findings from the 1990's, expanding the size of Troy with the "lower city" and adding much to our knowledge. I think the BBC series can be found on YouTube and is worth watching still, as it covers a lot of the same ground. I wish Schliemann had been more careful.
