Distilling 'helmet'
This 17th-century 'helmet' was not intended to be worn on the head, but for distilling liquids.
In Belgium, we know of no other such example. This makes the ‘helmet’ indispensable in illustrating the history of distillation in the Low Countries. In various 16th and 17th-century engravings and paintings, such as The alchemist by Pieter Bruegel from 1558, you can see how vapours were cooled down and converted into liquids in a helmet like this. These then ran into a jar or bottle.
