Schwabentor at Schaffhausen – unstretched

I used Microsoft Lens to unstretch this gate, a surviving artifact of the walled city of Schaffhausen – or, in the Alemanic language, Schaffhuuse:


Seeing this up close, it makes me wonder why the skin tones of some of the people in the painting are dark?  This might not seem interesting, but only about 300 m from this tower is the famous Schaffhausen Moor-fountain that portrays an Arab.

Could it be that Schaffhausen has a history involving the Arabs?  It would not surprise me, since Schaffhause is easily reached from the south of France via a long series of rivers.

It’s a mystery I have to come back and clear up some day!
