PICTURES TO SHOW THE FAULTINESS OF THE RESTORATION
|
These pictures will better explain Dr. Peratoner's article. The
importance of the modifications made by Mr. Brusa and Mr. Gorla during
restoration can be easily appreciated confronting the two following pictures
(even if they are taken from different points of view). |

The old clock frame with the 4 m. pendulum suspended on the SSE side of the building (right, on the picture), placed laterally and moved by a horizontal jointed arm. |
The new 1.90 m. long pendulum located on the north side of the main frame, far from the time train and beyond the striking mechanism. The suspension is of the spring type. The entirely new escape wheel can be seen together with the newly made split pendulum rod. Gorla had to use this solution to accommodate the axis to the north dial (towards the "Mercerie"). |

Drawings from the Technical Report by Annibale Marini
and Giovanni Doria (July, 22 1856) show the original position of the pendulum
assembly and the existence of the horizontal bar before De Lucia restoration,
carried out in 1858. The horizontal bar used to transmit the motion to the pendulum
can be clearly seen in the lower left side of the sketch and the Ferracina escapement
on the top right (Celestia Historical Archive of the Venice Municipality, 1855-1859,
III / 5 / 6 - Tower Restoration Works).

It has to be remembered that N. Erizzo, talking about the 1858 intervention, says that De Lucia added a device to the horizontal arm, but something is added to a mechanism, this means it already exists.
The presence of the pendulum in that position since '700
can be further proved by the suspension support (see picture below). This part
was no more in position since 1952 but is easily distinguishable and especially
its shapes corresponds exactly to the position where the pendulum has always
been. The support is made like the other static parts of the clock, in other
words it was made by Bartolomeo Ferracina. [See
Dr. Peratoner book, p. 37].

These pictures show the presence of the hole in the ceiling
of the building on the south side, which allowed the pendulum to oscillate.

The pendulum bob inside a glazed
box at the first floor of the Tower, in the position where it was before
the half 20th Century intervention. |
This picture shows how Mr. Brusa and Mr. Romanelli are
wrong when they say that the large panelled wheels (for hours and minutes indications)
are not compatible with the Magi's carousel. The large inner-toothed wheel on
which the figures were mounted has not been removed. It's clear that the tàmbures
were mounted over the Magi's mechanism without the need for its removal. On
the top of the picture, you can see the levers, which allow lifting the panelled
wheels during the carousel.
