@drewdevault interesting, I've been living in Brno for over a decade but don't remember this. For what it's worth maybe you'll be able to get some more background if you translate https://pamatkovykatalog.cz/alegorie-osvicenstvi-tolerance-19015365
It was originally part of a memorial for Joseph II. After independence from austro-hungarian empire I can see why it'd be considered in bad taste in the city center.
