Archaeologists want to use light to recreate the brilliant colors once seen on Trajan's Column in Rome.
The chaste white of Roman temples and monuments is a product of centuries of wear that has removed the original paint. The archaeology department in Rome is discussing the technical details of creating a light beam that would temporarily repaint the column, with the power company Acea and researchers at Rome University, the Italian news agency Ansa reported.
Sounds like a neat idea. I wonder how they'll do that.
