Day 30

Today in class we had another review day and we talked about Hellenistic Culture, it was very interesting. Hellenistic culture in a blend of Greek, Egyptian, Persian, and Indian culture. We talked about how Alexandria became the foremost center of commerce and culture/civilization. The main attractions of Alexandria were Alexander the Great's coffin (not actually alexanders body). A famous lighthouse named Pharos. And a huge library which had over 500,000 papyrus scrolls. The science and technology was a big part of the culture. Some famous astronomers were Aristarchus who found out that the sun is at least 300 times bigger than earth, and that earth and other planets revolved around the sun, Ptolemy who disagrees with Aristarchus and thinks earth is the center of the universe,  And finally Eratosthenes  estimated the real size of earth, also says its round. Unfortunately, by 150 B.C. Hellenistic culture is falling and Rome is on the rise.
