+modifications (not understood by Galileo) to the Dutch design, to do
+something no one took seriously. In the paradigm of the day, what could be
+the purpose of enlarging geometric spheres (planets) or points (stars)? In
+that paradigm only the position and movement of the heavenly bodies was
+important, and that had already been accurately studied (recently by Tyco
+Brahe).
