Howdy folks,
I know it's way past the time that an answer to this question would be used for the initial inquiry, but I have a good resource for others who may be interested
Saving Leonardo by Nancy Pearcey explores how cultural philosophy and world view have changed over time, and how those continuing changes have affected the works of composers and visual artists as a result. Well referenced with numerous examples, it's been a fascinating read and I highly recommend it.
Enjoy!
