Again, the Venetians fired cannons against the so-called "Elgin Marbles" until the last of them fell to the ground.

How have the Brits defaced them?

"Again, the Venetians fired cannons against the so-called "Elgin Marbles" until the last of them fell to the ground.
How have the Brits defaced them?"

They did not. A lucky shot ignited a Turkish powder dump located in the Parthenon which did a lot of damage, destroying the roof and knocking some of the sculptures to to the ground, but there are two very good sculptures and several partial sculptures that are still mounted to the Parthenon. There would be many more if not for Elgin.

Sixty years ago the Brits took chisels and wire brushes to the sculptures in order to make them bright and white, defacing them in the process.
