Anxiety" (detail), 1896, Edvard Munch. Taken by me at the Leopold Museum, Vienna.

I saw all people behind their masks – smiling, phlegmatic – calm faces – I saw through them and there was suffering – in all of them – pale corpses – who restlessly hurry – rush hither and thither – along a torturous path whose – end was the grave." (Edvard Munch)
