Well, I each of the four Greek words connects to a song from Bath/LYBM...two from each album. Oraios (beauty) = They Aren't All Beautiful, Topos (Landscape) = Geography, etc. SOMEHOW I know all that connects to the puzzle but I don't know exactly how.
Maybe the positioning of the tracks is part of it--I remember wondering why "Riseth He, the Numberless" was split into two tracks and eventually discovering that it was done in order to emphasize the albums' symmetry and enhance the puzzle. But I'm clueless as to what this, practically, means.
