OROLOGIO DE TEMPO VERO  -  SUNDIAL FOR TRUE SOLAR TIME 


 

Sundial for True Solar Time (25 KB) Explanations :

This sundial was the first Renzo Righi (designer) and Maria Luisa Montanari (artist) painted on the ‘casa Montanari’ in Cogruzzo in 1996. It appears simple in comparison to the later sundials.
On the dial plate hour lines are displayed for true local time from VII - XII - VI as well as the date lines for the equinox path and the solstices. The zodiac signs of Capricorn, Aries, Libra and Cancer are displayed in red beside it.
The green area between the hours XII and II have a meaning for the Islamic timing. There is also an Arabian inscription.
The artistic bordering of the dial plate featuring two snakes and a sunflower at the gnomon, a symbol of the sun, is remarkable.
There is a table of the Equation of Time (refer to the 2. picture) below the dial plate.

Gnomon :

A rod with a ball on the end serves as a gnomon for reading the time.
