No idea Keith, I have no access to her books, or the article. So I cannot verify whether that is indeed what she wrote, nor can I read the context in order to estimate how credible she was. Wikipedia states that she argued that Bruno was burned for espousing Hermeticism rather than Heliocentricity. But that is not so very different, as Hermetic thought had a huge influence on Medieval science, certainly on Newton, and possibly on earlier figures such as Roger Bacon. The killing of Bruno was an attack on all science, not just one aspect.
