Jeschke, Wolfgang. Das Cusanus Spiel
Divergence: 1452 CE
What if: Nicolaus of Cusa, cardinal, astronomer and philosopher, established a papally sanctioned academy to rigorously study unexplained phenomena.
Summary: In 2052, an Italian botanist becomes part of a papal project to restore central Germany and other areas devastated by a nuclear accident 20 years earlier, and then learns that her job will involve time travel to that region six centuries earlier.
Comments: Allohistorical content of the novel is limited to ten pages in the middle, from the original short story, which describes a timeline in which scentific development in Europe was jumpstarted in the mid 1400s. But the effects of rapid industrialization and development become problematic by 1900.
