For a time in the '-seventies of the last century, I walked every morning past the ruin of the "old" opera house at Francfort on the Maine. Upon the frieze appear writ large the words:
"DEM WAHREN SCHOENEN GUTEN" (for the true the beautiful the good). Inspiring are they not? I found them so, and I particularly approved of the absence of commas.
Since those days this beautifullest of buildings, erected originally in 1880, and having avoided a Minister of Finance's threat of entire demolition by dynamite, has been re-constructed. A very-large-scale photo-graph, wherein that frieze and its legend clearly appear, may be studied here:
