But that didn't work on every page.
But then, there was this new idea that came from a scientist studying spinach.
Yes. Spinach. This physicist, Uwe Bergman, does research that involves studying iron in spinach.
He was reading an article about problems with the palimpsest and it said that there is iron in the original Archimedes' ink.
So he came up with an idea to use the same method of looking at iron in spinach to view the iron on the palimpsest pages.
And his idea worked.
Bergman's technique allows X—rays to pass through the forged paintings, pass through the scribe's writing to hit the iron traces from the ink of the original Archimedes' text and create an image just of the iron on the pages.
The iron—based letters seem to just pop off the page.
The original text and diagrams emerged, line by line, diagram after diagram.
And that's kind of typical of our field.
There's a lot of interdisciplinary work.
People from several different fields might be involved in working with a single art.
