The entire medieval period was ignorant due to the despotism of the catholic church. There are numerous ignorances.
Needless to mention Copernicus, Kepler, Galileo and Newton. The fact that disagreeing with the church on anything, disagreeing with Aristotle or decrying revelation as a means of knowledge was punishable by death, are all good examples of this, but I'm interested to see what others dig up because these are rather general.
More specifically, perhaps, is the belief that a supernova was within the atmosphere. not as if that would have any adverse effects, eh boys?

Religion is an attempt to answer the philosophical questions of the unphilosophical man.
