I saw this story a little while ago. It's good to see another Cimabue discovered considering how little of his work has survived. His frescos from the Church of Assisi oxidized to such an extent that they look like old photographic negatives:
His masterpiece crucifixion housed in the Church of Santa Croce, Florence, was horribly damaged by the great Flood of the Arno:
Perhaps his finest surviving works are the Maesta...
... and the Santa Trinita Madonna:
This loss is all the worse when one recognizes that Cimabue was the father of the Florentine Renaissance... the immediate precursor to Giotto.
