Ancient Rome was really impressive. It absorbed a lot from ancient Greek and ancient Egyptian culture and technology, and did a lot of things that should have been done. In terms of mythology, they directly copied the ancient Greek mythological system, and their sculptures were also influenced by ancient Greece. They even managed to create glass, which is amazing. Compared to the Middle Ages, Rome was truly dominant; the Middle Ages were indeed the dark ages. The Renaissance was truly a revival. After the Renaissance, maritime technology absorbed a lot of Islamic navigation techniques, leading to a surge in various technologies. For example, the clock technology of the fifteenth century was completely ahead of its time. No wonder they sent clocks to the Emperor of the Qing Dynasty, but unfortunately, the Qing Emperor didn't recognize their value. Behind clocks lies mathematics, mechanics, processing, and materials—a complete set of scientific technologies.
