The first rotavap?

In this post I said that Lyman Creighton Craig invented the rotavap (1950) and that Walter Büchi made the 'modern design' (1957). I may have been wrong.

Is this alchemist using a rotavap almost 2 centuries before Craig?
The Alchemist in Search of the Philosophers Stone, by Joseph Wright of Derby, 1771.

That painting is on the cover of last year's Aldrich catalog. I always assumed the apparatus was basically a chimney to pipe noxious fumes outside.

It's so obviously a bong. Look at the stoned lad at the table lighting up.
