" Medieval Romans colonized the vestiges of the ancient city as sea creatures might a sunken ship. Amphitheatres and temples were turned into fortified strongholds; the monuments of the imperial capital were used as quarries for building materials. An entire neighbourhood was devoted to burning classical marbles, sculptures included, to turn them into lime: steadily reducing the glories of antiquity to powder. "
― Martin Gayford , Michelangelo: His Epic Life
