About this source

What it is

This hand-coloured engraving from 1547 shows a set of ornate vessels, including spheres and urns, some with jets and some with smoke or steam rising from their lids. These objects are versions of the aeolipile, a steam-powered device.

Why it matters

The aeolipile is one of the devices credited to Heron of Alexandria, who described how heated water could produce steam strong enough to move or spin a vessel. This 1547 image shows that, over a thousand years later, European makers were still building and illustrating decorative versions of his invention, treating it as both a curiosity and an object of craftsmanship.

Look closer

  • What details suggest these vessels were made to be admired as decorative objects, not just scientific tools?
  • How does the artist show that steam or smoke is coming from the vessels?
  • Why might craftsmen in the 1500s still be interested in a device first described in antiquity?
