Text: But Assisi's frescoes of the saint's life, painted by Cimabue and disciples of Giotto (which barely survived the severe earthquake of 1997), proved an immensely effective act of artistic propaganda against the prevalent libertinism and heresy.
Entailment: The frescoes of Assisi were inspirational to those who opposed libertinism.
Contradiction: The saint believed in living a self-indulgent lifestyle.
