Some friends and I visited an FSSP parish called St. Anne's this last Sunday. It was a High Mass, and at the consecration when the sanctus bells were ringing, the big church bell outside was rung at the same time. How cool is that? I suppose the neighborhood had no idea what it meant, but what a neat idea to broadcast the miracle that's happening inside to the outside world. Maybe some lapsed Catholic heard it and felt guilty. :)
I read somewhere that in the 15oo's in England it was made illegal to ring a church bell nine times at 6 am, noon, or 6 pm. The Angelus is traditionally sounded at those times with three sets of three bells. So that's how we know that the Angelus was popular in England when it was a Catholic country.
And of course Paul Revere's friend hung a lantern aloft in the belfry arch of the old north tower as a signal light.
I've now exhausted my church bell lore and will end this post.
