In investigating old churches, watch in the later ones for the influx of ordinary people, bodies, faces. It looks like the 1400's marked a change: regular folk replacing the saints, that had peopled the churches in the centuries before the 1400's or so. Individual expressions, tastes on clothing, headwear. Hardly inspiring in the sense of recalling to a worshipper the story of the martyrdom or whatever; but far more interesting. This is not just a protestant trend: look at this Catholic church in Sibenik, Croatia, with its human faces circling the exterior, at Sibenik, Cathedral of St. James, Croatia.

The pulpit in the Deutsche Kirche is hewn from a single tree trunk, oak we understand. It dates from about 1484. Note the three dimensional areas. The pulpit looks alive, with branchings.
Then see the French Gothic church (Roman Catholic), dating from about 1481. It replaced an earlier St. Catherine's Chapel and has some replacement stained glass windows that are modern and very bright.
