Yesterday, reading about the disaffected and dissentient protestant scholars of the 30 Yrs War ("Hey, I've just heard the first shot of the Thirty Years War..."), my mind and spirit was very much in the old buildings and neighborhoods of Transylvania -- Sibiu, Cluj, etc.
Sibiu was the old capital of the heptarchy, and some of those structures still survive -- churches, bookstores, coffeehouses, etc. Refuge for the Socians and a-Sociated anti-trinitarians. (Many of whom were quietly alchemists and devoted readers of curious old books.)
