Astronomy, celestial mechanics and the observation of day and night cycles led us to develop devices and scientific instruments that helped us to create mathematical patterns to measure the time of light and darkness.
Compass sundials, introduced in the 15th century, were the first portable sundials. The compass allowed the instrument to be orientated for its correct function, the quadrant is aligned to the south and the gnomon (a piece of rope or a foldable triangle) casts a shadow indicating the solar hour in the hour quadrant. The heyday of sundials lasted from the 15th to the end of the 18th century.
The Pizarro sundial is a scientific instrument that is both decorative and functional, as it indicates solar time. Its rectangular shape and meticulous decoration make it an original and indispensable gift for sensitive people with an intellectual interest in science and astronomy or for the sheer pleasure of owning a historical ornament and collector's item.
