Premise: In the Upper Basilica, reopened in 2000 after intense round-the-clock restoration, Cimabue's works in the apse and left transept have turned black, looking like photo negatives because of the oxidized white lead in his paints, yet you can still feel the intensity of the crowd's anguish in his Crucifixion, blessedly untouched by the earthquake's damaging force.

Hypothesis: The Upper Basilica was never reopened because of the extensive damage.
