Giovanni Luigi de Fiesco, Duke of Lavagna, who lead a revolt against Andrea Doria in Genoa 1547. The revolt was a total success until he stepped on a plank to enter a ship and slipped. Wearing his bling-bling armour he sunk like a stone....goodbye Mr. Fiesco. They found him 3 days later on the shores.

Imagine this as a movie...everbody would say:" This ending is not very comprehensible!"...Well, Schiller actually made a drama about the revolt in 1547.
