That is a compliment! Being erudite means that you have or show a wide knowledge gained from reading; learned; scholarly.
Someone called me erudite. Is that good?
Readers cannot fail to recognize Dante's erudition. He appears to have taken all learning for his province, or what passed for learning then. The fact that much of the scientific teaching was hopelessly in error is not Dante's responsibility. The fact that he displayed extraordinary curiosity and avid interest in all branches of scientific learning (geography, geology, astronomy, astrology, natural history, and optics) reveals something important about the poet's mind.
