Fellow AWAD person Rubrick has cleverly combined the name of a building at Trinity with a nod to the beautiful red brick of said building. Which got me to thinking: "rubric" originally coms from the Latin for red, doesn't it?

I checked. It does. Very cool.

Which brings me to the expression "sub rosa," which far as I remember, means "between me and thee." I'm having trouble looking that one up. As I recall, it coms from some English monarch (Tudor = rose?) who liked to receive visitors in his bed, on the wall above which was painted a rose. This is bugging me, can someone set me straight on the origin?
