Yep. And I learned that pendentives are better. Your age is showing.

Sign you,

Mr. Archaic.

If you're more archaic than I am, you're way too archaic.

 

For some reason which I no longer remember, I thought there WAS a difference between a squinch and a pendentive, but from my moments-ago reading of Saylor's Dictionary of Architecture, they seem to be the same.  CRS, indeed.
