Our information about the early stages of Greek music is so slight that these references of Aristides Quintilianus to an the Pseudo-Plutarch to a scale employed by the legendary figure Olympus take on an immense value for us. The dialogue itself is an unskilful patchwork, but the author's sources are often good. These particular passages are almost certainly both derived with small alteration from Aristoxenus, in whose time the traditional music ascribed to Olympus was still in use. For the elucidation (...) of the scale's history and structure we have three1 pieces of evidence to help us. There is the first passage mentioned above, which deals with the discovery of the enharmonic genus by Olympus, which is connected, at first sight obscurely, with the Spondeion scale; and the second passage, which discusses the scalar limitations of theσφoνδειξων τρόφoς with especial reference to an elementary polyphony. There are also the ancient scales quoted by Aristides Quintilianus. (shrink)
