Theming Bonus List

I have never been able to get any bonus from the Hermitage. I have had met the criteria, and tried every possible combination as well in case the doco was wrong. I have managed to get all the others fine, so I am capable, but obviously not for this particular building.

Am I the only one with this problem?

i dont understand how to get the max bonus i had 2 works of writing in the great library both were from different era and different civs yet i only got +2?

@OP:

You forgot to mention that listed theming bonuses are after adopting aesthetics branch finisher numbers

Anyone know if any modded Wonders get a bonus? Specifically ones like Abu Simel, or the Crystal Palace?

I'm pretty sure they can because the Santa Del Fiore wonder associated with Tuscany Civ has one.
