In thinking about the history of music, have you ever considered Spengler's divison of the last, three millenia into three, equal parts of 1000 years each? You know, the Apollonian (Greek and Roman): 1000 BC - O, the Magian: 0 - 1000 AD, and the Faustian: 1000 AD - 2000 AD?
All of these ages began with architecture (the first art) uniquely their own, and, according to Spengler, spoke volumes about the people who built them. The Apollonian culture, which died at the Battle of Actium, (so Spengler) lacked the interiority of the Magian culture that followed. It's temples were not meant to serve any congregation, and were basically, banks, or vaults, wherein a city might keep its valuables. As Spengler put it, if I remember right, the Apollonian temple began on the outside - and stayed there, as opposed to the Magian, which, based on the Syrian domus, began on the inside, and stayed there. The Apollonian temple was little more than stele in the round and meant to impress the world of the outside.
The Faustian temple is the Gothic catherdral, and was all about light, and escape, as Spengler put it, into the beckoning, pure thither. The Gothic catherdral begins with polyphony (c. 1000 ), and, it seems to me, the lightness of the Gothic style, the welcoming of natural light into the inner most sanctum, is continued on through the history of Faustian art, which becomes ever lighter as its millenium moves on: architecture, sculpture, painting, literature, music, and so on. It seems as though the denser the population, the lighter the art. Do you have any thoughts on this? Am I barking up the wrong tree?
