G. A. Magnini.
It would be more difficult to name a scientist in Galileo's day who did not subscribe to Aristotelianism where the "natural" sciences were concerned. Galileo represents a manner and degree of inquiry that outstripped the best of them. Fortunately he did not give up in the face of persecution.
Today the picture is much the same. The power, authority, egoism, and ignorance rests in the hands of a few who bring only unjustifiable bias to the pursuit of knowledge, namely dogmatic evolutionists.
The University of Bologna was the preeminent Catholic university of its era. Its administration was led by bishops and cardinals; the papal legates were its supreme authority (source: New Advent). So, there is no clear basis that I can see to conclude that this G.A. Magnini is a "secular party" unless there's something more to go on. The text linked above does appear to suggest that Prof. Magnini had not viewed Jupiter through a telescope, for whatever that's worth..
Whatever the case may be, this G.A. Magnini is a rather flimsy basis upon with to make such a sweeping insinuation. LOL
Fortunately my local library has a copy of the text cited at the above reference to this G.A. Magnini. I've made a note to myself to check into it when I return some books next week, and I'll get back to you on whether it provides any further insight on his character and rationale.
