Skein Dial, Hannah Imlach, 2023. Art installation and sundial at RSPB Loch Lomond, with the artwork constructed in Corten steel in the foreground and the towering mass of Ben Lomond in the distance. This is a remarkable piece that captures the ephemeral impression of geese in flight and shows the dates when they migrate by a sundial shadow. Photo: Hannah Imlach
In November 2022 visual artist Hannah Imlach approached us to talk about an art installation she had in mind for the RSPB Nature Reserve at Loch Lomond. The reserve is a prime site where Greenland White-fronted geese come and overwinter. Hannah’s concept for her artwork was a visual image of skeins of geese flying in the sky combined with a sundial showing the times when the geese arrive and leave. White-fronted geese migrate from Greenland in the autumn and return there in the springtime to breed. Continue reading
This is the analemmatic type of sundial that lies flat on the ground and the person casts the shadow to show the time.
The coastal trading and industrial town of Kirkcaldy in Fife, Scotland, was famous up to the 1960s for its linoleum. In an earlier age, Adam Smith the 18th century economist and author of The Wealth of Nations was born in the town. Sandford Fleming was born in Kirkcaldy on 7 January 1827. He pioneered the changes to standard time and time zones for the whole world. Continue reading
The shadow of the ball on the sundial follows the sun all year round. The sun is low in the sky in winter, and it reaches its lowest point at the Winter Solstice on 21st December. This photo is one month later on 20th January. The sun is already higher in the sky, and the ball’s shadow has moved down.
Sundials catch a shadow from the sun. It is such a simple idea. The shadow on the sundial shows the sun’s position in the sky and the sundial reads it out as time, usually the time of day and often the time of year as well. Our armillary sundial is a special one with two balls that give the time of the year measured by the height of their shadow at noon. One ball casts a shadow in the winter months and the other one in summer. Continue reading
We shot this impossible photo blind because there is no room to stand between the sundial and the house wall.
Dihelion is our well-known dual sundial design, which reads solar time and solar declination. It is impossible to take this photo in the normal way because the sundial is too close to the house, and there is nowhere to stand. So the photo was taken by holding the camera against the house and shooting blind. At a first attempt, the picture has turned out well. Continue reading
A new design of armillary sphere takes shape in Edinburgh, inspired by an original sundial from Northern Italy. The skilled blacksmith work is complete. This is a bespoke design with gold highlights still to be painted.
A new design of armillary sphere has been taking shape in Edinburgh. It is inspired by an original sundial from Northern Italy which has an attractive and distinctive form. The expert blacksmiths at Ratho Byres Forge have done an excellent job in working from our design. Continue reading
Time lapse camera set up for study of a sundial looking at precision of the time shadow
There are many interpretations of how well a sundial reads the time. It is often thought the smallest increment of time on a sundial will be around two minutes. This is because the large diameter of the sun gives a fuzzy edge to the time shadow. Our study looked at the shadow Continue reading
