The BBC’s arts editor Will Gompertz told Radio 4 that “the ink from the pen has bled all the way through the canvas causing a deep wound, not a superficial graze.”
“Because of the way in which Rothko worked, which was building his paintings layer after layer after layer in a meticulous fashion, the conservators are going to have to remove the paint layer after layer and then rebuild it.” Gompertz explained.
The man who scrawled a message on the painting as it hung in the Tate Modern said at the time:
“I didn’t destroy the picture. I did not steal anything. There was a lot of stuff like this before. Marcel Duchamp signed things that were not made by him, or even Damien Hirst…I don’t believe that what I have done is criminal. If the police are going to arrest me, then they are going to arrest me. I am OK with that.” the man who called himself Vladimir Umanets said at the time.
He was later revealed to be a Polish man by the name of Wlodzimierz Umaniec, who appeared at Camberwell Green Magistrates’ Court in October this year and pleaded guilty to the charge of criminal damage.
