The two pictures in the post below are of Tyn Church, which stands taller than anything else around Prague's Old Town Square (for a quick reminder of how old Prague is, realize that New Town was built in the fourteenth century.) N. and I spent 2 of our three days in Prague wandering through Old Town, so we spent a while looking up at the spires of Tyn Church.
The golden image on the front is the Virgin Mary, but it used to be a chalice. That's because Tyn Church was once a center of the Hussites, whose main break with the Catholic Church was over whether lay-people should receive Communion wine as well as wafer.
The Hussites, so named for their support of Jan Hus, split from Catholicism more than a century before Luther did. And they didn't simply disappear either. Tyn Church was held by Hussites until 1626, and today's Moravian Church claims direct descent from Jan Hus.
