    Astronomy made up the majority of the Scientific Revolution, and only a few significant figures made significant advances in Astronomy, while church dogma hindered many efforts to make sense out of rational theories that were opposed to the Holy Scripture.

When the West was sufficiently mature to feel the need of deeper knowledge, it turned its attention, first of all, not to the Greek s...
