Christian Science was founded by Mary Baker Eddy in 1879. It’s a variant of Christianity that basically views Bible teachings through the filter of her book, Science and Health with Key to the Scriptures. There are some 100,000 members of the Church of Christ, Scientist, spread among some 1,700 churches across the world and Mary Baker Eddy also built an 80-year-old, stained-glass globe that you can walk inside call it the Mapparium.
The Mapparium is a full sphere that stretched above, below, and beside us in an aurora of blue ocean that gave the space somewhat of a bathysphere effect. The landmasses were color-coded by country in a small spectrum of hues that did little to counteract the blue glow.
It is some kind of futuristic meditation chamber or antique observatory. The map shows the world as it was in 1935, when the Mapparium was built. So the USSR was a massive unified splotch of red. Africa bore a few names that have been changed multiple times over the years.
This wonder of a world is at the Mary Baker Eddy Library at 200 Massachusetts Avenue in Boston, right at the edge of Christian Science Plaza.
