BISHOP MARTENSEN was in his official residence, standing slightly concealed behind a curtain. The niche by the window provided an excellent view across the square adjacent to the Church of Our Lady, with the Metropolitan School in the background, the University of Copenhagen on the left, and the Church of Our Lady itself on the right. It was Sunday, November 18, 1855, just before two o’clock in the afternoon. All at once a crowd of people dressed in black practically burst from the church, gathering at first in small groups, then disappearing in every direction.
