1871. that was the year of the first renewal proposal of Pincio’s boulevard by the Administration of Rome. The goals of that renewal were the creation of a new water container and several re building works. This ambitious initiative involved two high personages: Giovan Battista Embriaco e Gioacchino Ersoch.

It was 1867 when Giovan Battista Embriaco, a Dominican father who had created several clock gears, presented two prototypes of the Hydrochronometer to the Paris Universal Expo, obtaining great success. One of that clocks would become the current Pincio’s Water Clock.

Gioacchino Ersoch took in charge the maintenance of the new water system and of Clock’s aesthetics , and he choose a complex arrangement: a kind of wooden “chest” which looked like a pinnacle to include the mechanism, placed on a small rock in the middle of a folksy lake.

In 1872 Ersoch’s project and Water Clock’s project, which were initially separated, were put together.

1873. The Water Clock arrived in Rome. The art work have dials that remember a tree’s transverse section and hands plant shaped, and it’s in harmony with the natural context of Villa Borghese.
