Take the following as truth: Several priceless frescoes were severely damaged or destroyed, notably invaluable works by Cimabue (1226 1337) featured on a portion of the Upper Church's vaulted ceiling, which plunged to the floor during the quakes.
Then the following statement: "Cimabue was an Italian painter well known for developing his own painting style and being all self taught." is true, false, or inconclusive?
