Hi Petra & All,

Looking at the balcony/awning in the upper left corner of the painting and assuming it is level (ie the same as the horizon) and measuring the angle of the shadow it casts with a protractor, the angle of the shadow is 36 degrees -- indicating the altitude of the Sun is about 36 degrees.

However, Paris is at approximately 48 degrees N and given the Sun is in Ophiuchus on 2 December at about 22 degrees S declination it means the maximum altitude it attains on 4 December is about 20 degrees.

You cannot determine the time from the painting because the Sun is at an impossible angle for 4 December.

Best,

L.
