10 Things Invented Way Earlier Than You’d Expect

8. The Wonders of Ancient Transportation: The Aeolipile

The aeolipile, often considered the first recorded steam engine, was invented by Heron of Alexandria in the 1st century AD. This simple yet ingenious device consisted of a hollow sphere mounted on a pair of tubes, which allowed steam to escape and create rotational motion. Although primarily used as a novelty or demonstration of the principles of steam power, the aeolipile represents an early understanding of the potential of steam as a source of energy. Heron's invention laid the conceptual groundwork for developing steam engines in the Industrial Revolution, transforming transportation and industry. The aeolipile is a testament to the innovative spirit of ancient engineers and their ability to envision the possibilities of harnessing natural forces. It serves as a bridge between ancient experimentation and modern technological advancements, highlighting the continuity of human ingenuity across the ages.
