On Thursday I got not only a postcard but also a cover from Germany.
Naumburg Cathedral (issued 06-10-2016)
with a special postmark about the 475th anniversary of the inauguration of Nikolaus von Amsdorf as Bishop of Naumburg-Zeitz
Nikolaus von Amsdorf was born in Torgau in 1483. He was a German theologian and one of Martin Luther's most determined supporters. In 1542 he was installed as Bishop of Naumburg-Zeitz and thus became the first Lutheran bishop in Germany, but already in 1546 he had to left his position. He died in Eisenach in 1565.
