The Meaning of Materials by Frank Lloyd Wright

1. I know Wright is a visionary when it comes to architecture and design but his writing... and this is based off of the 2 readings we've had from him, I'm not a fan.
2. good quote: "each material has its own message and to the creative artist, its own song."
3. stone is the oldest building material known to man
4. why does a block of stone have to be a square? is that more structurally sound than say a rectangle?
5. why in his opinion did the Greeks ruin stone?
