| This group was later joined by the Greeks who recognized that the oceans have currents as they ventured out of the Mediterranean into the Atlantic Ocean. A hundred years later, the foundation of celestial navigation was being developed at the Library of Alexandria (the oldest known university), Egypt, by a Greek named Erastosthenes. He developed the concept of locating places with lines of latitude and longitude, and hence, produced the first chart of the Mediterranean "world." Around 200 B.C., he used an ingenious method to calculate the earth's circumference, overestimating to less than 200 km of the true circumference. This calculation revealed that the Earth was very large. |
