Ancient Greek "Computer"

Ancient Greece was home to the world's first known computer, known as the Antikythera mechanism. This complex, ancient Greek device dates back to around 150-100 BCE and was discovered in a shipwreck near the Greek island of Antikthera in 1901. The mechanism is composed of a series of bronze gears and dials, and it was used to predict astronomical positions eclipses, and even the dates of the ancient Olympic Games. The sophistication and precision of this technology is astounding, considering it was created more than 2,000 years ago, and it demonstrates the advanced understanding of astronomy and mathematics in ancient Greece.
