A Philosopher, by Jusepe de Ribera (1637)
A long time ago at a university far, far away:
The rector complains while talking with the dean of the department of chemistry:
you, chemists, always expect from me a lot of money for your laboratory equipment. You are going to ruin all of us!
Look at the mathematicians: they just need pens, some paper, and trash cans.
Or look at the philosophers: they only request for pens and paper!
