Arnold Böcklin, Roger and Angelica, 1871-1874, Nationalgalerie, Berlin

The guilty expressions on both the maiden’s and the monster’s faces are priceless. Clearly, “Roger” (better known as “Ruggiero”), in Böcklin’s imagination, was interrupting just as Angelica and the monster were “getting to know one other better.”
