In those days a man could not go from the Rose Tavern to the Piazzi once but he must venture his life twice.
Piazzi called it Ceres, after the tutelary goddess of Sicily.
It was in this locality that Piazzi discovered the asteroid Ceres, January 1, 1800.
The Piazzi Sopramuro is one of the oldest parts of the town.
It was on the 1st of January, 1801, that Piazzi commenced for the one hundred and fifty-ninth time to observe a new series.
The attempts of Piazzi and Brinkley, early in the nineteenth century, also failed.
Oddly enough, Piazzi was not one of the twenty-four astronomers who had agreed to find the new world.
Piazzi fell back upon pagan mythology for the name of his little world, and called it Ceres, from the Roman goddess of corn.
The Piazzi del Municipio was the scene of many conflicts in the troublous days of Perugia.
Piazzi noticed a considerable increase of lustre in a very faint star of the twelfth magnitude viewed through a comet.
