That comes with punishing scientists for learning.

Please note that this list is only of scientists and mathematicians who were also Catholic clergymen. Non-clergy Catholics are in a separate list.
Right, I wasn't saying the Church was entirely hostile. The astute reader will have noted that I was pointing out that medieval rulers were quite happy to use religious justification to secure their earthly positions. An even-smarter fella might have noticed that this Church didn't bother to object -- unless said regent interfered with that Church's own Earthly concerns.
