About this source

What it is

This is a computer animation made in 2021 by a hobbyist, MichaelFrey, showing how the aeolipile described by Hero of Alexandria may have functioned.

Why it matters

The aeolipile is one of the earliest known devices to turn steam into motion, credited to Hero in his ancient writings. This animation is a modern, simplified explanation, not an ancient image or record, but it helps explain the mechanical idea behind Hero's invention.

Look closer

Is this animation made by an expert historian or an amateur enthusiast?
