Sundials are the oldest scientific instrument of all and are of great historical importance. Originating as early as 5000bc as simple sticks in the ground sundials developed over the centuries to become accurate measures of time.

In 250BC the Greeks started to construct complex sundials. In about 100BC the 'Tower of The Winds' was completed in Athens. This tower had an octagonal shape and each face contained a sundial.

Why have a sundial in the garden?
Sundials came be a fascinating architectural feature in the garden or public park. Sundials are intriguing and can be a great educational tool for children. Sundials also provide us with an historical link to early astronomical practices. Powered only by the sun itself, sundials add a sense of timelessness which is interesting for something that tells the time. Sundials can also be a great feature in a smaller courtyard.

How Sundials Work
Sundial work using mathematical principles to have the sun cast a shadow on different parts of the sundial at different times of the day.

Types of sundials

Horizontal sundials are probably the most common. This type of sundial is usually mounted on a pedestal but often set into the ground itself.

Vertical or 'declining sundials' were set onto the walls of churches and other south facing public buildings

Equatorial Dials were based on the armillary sphere, much more complex than other sundials Equatorial Dials certainly create a sculptural effect and make a great talking point as well as an historical reference.
