made by Gaurav owner by zpixol studio By 1531, after the death of Carlo Raineri, the clock was already not working properly. The Council of Ten decided that a permanent keeper must be appointed to live in a wing of the tower and be responsible to keep the clock in working order. Later, in 1551, Jacopo Sansovino, then the architect responsible for St Marks, was instructed to report on the state of the tower and clock. Major repairs were required, but by 1581, when his son, Francesco, published his description of Venice, all appears to have been in order.
