What legacy did roman culture leave in the fields of astronomy, anatomy and geography?

Medical practitioners in ancient Rome not only utilized all available tools to their best, but also developed as many new tools themselves and efficiently devised the use of cesarean section. But they made the biggest of leaps in battlefield related surgery by making medical preparedness and remedy in battle a prime concern. During the reign of Augustus, the military medical corps was established to assist injured soldiers in battles. The Romans also mastered medical innovations to curb immediate blood loss in battles, thus saving thousands of lives. They also invented tools like bronze scalpels, obstetrical hooks, bone drills and forceps, and also the rather frighteningly named vaginal speculum. The Romans are also attributed with pioneering the earliest form of antiseptic surgery since they used to dip medical tools in hot water to disinfect them before surgery.
