Nicholas I (reigned 1825-1855): it shows the profile of his daughter Olga in the center. (Wikipedia tells us that she met her future husband, Crown Prince Charles of Württemberg, in early 1846 in Palermo, Two Sicilies, so perhaps the table commemorates that meeting, though we are not told what she was doing there, so far away from home and — presumably — her chaperons). The table represents views of famous bays of the Kingdom of Both Sicilies: Naples, Taormina, Palermo, Paestum, Tindari.
