We got to Robert Fludd through Thomas Cromwell. It doesn't make much sense at first (but neither did Fludd most of the time). Really, it is Hilary Mantel's fault. While waiting for the third part of the Wolf Hall trilogy to come out, we read her older books, including Fludd. That made us wonder about the real Fludd which brought us to his Philosophia Moysaica (Gouda: Petrus Rammazenius, 1638).
