What does it mean for the Pergamum Museum that a jew built it?

[Novice Priest Karnonnos]

That's life. This Jew and his family accumulated gargantuan amounts of wealth, study and connections, therefore had extensive buildings designed and created as an architect. You want to do anything? You get to that position. Lesson learned.

Question every single thing ever and nothing will be pure or perfect enough.

Wilhelm von Bode was the one who ordered the creation of the Museum in the first place.
