And notice, at first, there was a most beautiful church, but a wicked man destroyed it, and only the base remains, which is stone, and the center of the church has columns.

A manuscript illustration shows a religious complex representing the Mount of Olives and the Church of the Ascension. The central structure features a three-arched portico beneath a large dome topped with a crescent-like finial. Figures, representing Christ and his disciples, are visible inside the arches. A white path leads up to the building, containing a dark grid pattern and a figure.
