In 1730 he abdicated in favour of his son, Charles Emmanuel, retired to Chambery, and married the countess of San Sebastiano (afterwards Marchioness of Spigno).
Another LUIGI MOCENIGO was doge from 1700 to 1709, and his brother SEBASTIANO from 1722 to 1732.
As the duties of this council were to appoint all officers of state, including the doge, it is clear that by its creation the aristocracy had considerably curtailed the powers of the people, who had hitherto elected the doge in general assembly; and at the creation of Michiel's successor, Sebastiano Ziani (1172), the new doge was presented to the people merely for confirmation, not for election.
In the district that bore this designation, lying close to the Appian Way, the basilica of San Sebastiano was erected, and the extensive burial-vaults beneath that church - in which, according to tradition, the bodies of the apostles St Peter and St Paul rested for a year and seven months previous to their removal to the basilicas which bear their names - were, in very early times, called from it coemeterium ad catacumbas, or catacumbas alone.
The first enlargement of the square was effected by Doge Sebastiano Ziani in 1176, when he filled up the canal and rebuilt the church on a new site at D, thus nearly doubling the size of the square.
