The sundial in the extent of 370 X 350 cm at a vertical wall features two separated dials, each with
a gnomon and the seven zodiac datelines.
They show the Temporary Hours (HORAE PLANITIAE) and the astronomical time rising and descending from
the equinoxes at springtime. The descending sector is outlined by the curves of the maximal declination
of the moon and characterized by the hour lines of the night produced by the moonlight. The sub
division of the dial plate allows the half-yearly display of the solar and lunar eclipses of the years
2000 to 2020, visible in Italy. The path of the planet Saturn is shown between the different signs of
the zodiac for the same time period.
An artistic ornamentation is a serpent with a locket featuring the seven planets. To the left, Pegasus
jumps out of the clock face. In his shade, the constellation of the Pegasus may be recognized, above
it the full moon. Below there is a card with the sidereal rhythmus of the moon (RITMO SIDERICO della
LUNA) and a small card with the crescent and the half moon. Finally, there is another sunflower on the
right side below on the wall cornice.
