For example, a sundial designed for a latitude of 40° can be used at a latitude of 45°, if the sundial plane is tilted upwards by 5°, thus aligning the style with the Earth's rotational axis. [citation needed] Many ornamental sundials are designed to be used at 45 degrees north.

Wegner had a grand oval driveway built in front of the main building with a sundial in the middle of the lawn. [1] The sundial is constructed as an open globe, where the meridians cast a shadow on sunny days onto the inner part of the globe, hitting the inside of the equator line and thus showing the time, specifically the astronomical solar time.
Early examples of the use of garden ornaments in western culture were seen in Ancient Roman gardens such as those excavated at Pompeii and Herculaneum.The Italian Renaissance garden and French formal garden styles were the peak of using created forms in the garden and landscape, with high art and kitsch interpretations ever since.
The Sundial (Norwegian: Soluret) is a sculpture that is part of the Vigeland installation in Frogner Park in Oslo, created by Gustav Vigeland. It is a sundial that stands on a pedestal with granite reliefs between the Monolith and the Wheel of Life. The sundial dates back to around 1930. [1]
An analemmatic sundial uses a vertical gnomon and its hour lines are the vertical projection of the hour lines of a circular equatorial sundial onto a flat plane. [6] Therefore, the analemmatic sundial is an ellipse , where the short axis is aligned north–south and the long axis is aligned east–west.
The style of the equatorial sundial is parallel to the Earth's axis of rotation. This type of sundial is known as an equatorial sundial because the plane of the dial face is parallel to the Earth's equatorial plane. Two primary examples of modified equatorial sundials are bowstring equatorial and armillary dials. [9]
A Butterfield dial is a portable horizontal sundial designed to be folded flat and used in latitudes between 35° and 60°. It was named after the English gnomonist Michael Butterfield, who was active in Paris around 1690.
