If not for concrete, which the Romans invented, some of ancient Rome would not have been built at all. They had some amazing architecture. The Colosseum alone, according to Google, is the largest standing amphitheater in the world today.

I worked on the designs of a line of furniture that we called Darby, which included a lounge chair, ottoman, dining chairs, bench, sofa, and settee. It started with the lounge chair before I was there, and then I worked on the rest. I made full-scale cardboard models of the dining chairs and bench. Back legs of the chair are laminated cardboard, to illustrate the curves. That's my only experience with Darby. We had a CFO named Joan.

Interesting that many of our common phrases are from Shakespeare. I wish I paid more attention in high school :-/

Handwriting on the wall This phrase is often heard as a portent of doom. “When the candidate saw the early returns from normally ‘safe’ wards, he know they were the handwriting on the wall and that he was doomed to defeat.” The expression was inspired by a line from the Bible (Daniel 5: 25-31). Belshazzar learned that he was about to lose his kingdom when the words “Mene, mene, teckel, upsharsin” magically appeared on the wall of the place “This is the interpretation of the thing . . . God hath number they kingdom and finished it . . . Thou art weighed in the balances and art found wanting . . . They kingdom is divided, and given to the Medes and Persians.”
