Detail of this sundial

A particular detail of this sundial.

This sundial was calculated for the south facade of the Bastide des Moures situated in the municipality of the Thoronet (Var 83).

This is a precision dial, vertical declining type.

It indicates the solar time of the place as well as the height of the sun in the sky.

Its motto is from Frédéric Mistral. It means “life is only a reflection of sun” in Provencal.

 

A short video on the engraving of the dial…

The simple movement of shadow on lines engraved on the stone, hides the complex study of the movement of the Earth around the sun.

 

We make different types of sundials (horizontal, vertical, equatorial,…), all sizes (from the small to the monumental one).

These dials can indicate seasons, astrological signs, a particular date (inauguration, birthday,…).

You can choose inscriptions and ornamentations that you wish.

Each sundial is accompanied with its personal manual.


 

Do not hesitate to contact us, so that we can create together, your personal sundial...
