Festa della Sensa
The Fèsta de ƚa Sènsa was a feast of the Republic of Venice held on the occasion of the feast of the Ascension and still celebrated as a recreation today. It commemorated two significant dates in the Republic's history; the first being May 9, 1000, when the Doge Pietro II Orseolo rescued the denizens of Dalmatia imperiled by the Slavs. The aforementioned date marked the onset of Venetian extension in the Adriatic.
. Another painting of the same subject by Canaletto, Il Bucintoro al molo nel giorno dell'Ascensione, was purchased for £11.43 million by a mystery bidder at a Christie's auction in London on 6 July 2005.
The second event commemorated took place in 1177 when the Doge Sebastiano Ziani, Pope Alexander III and the Holy Roman Emperor, Frederick Barbarossa agreed to the Treaty of Venice which ended the long-standing differences between the Pontificate and the Holy Roman Empire.
On the occasion of this festival was held the ceremony of the Marriage of the Sea. This ceremony is recreated annually with the Mayor of Venice taking on the traditional role which was historically executed by the Doge.
