Rustic stone sundial in an Edinburgh garden

A stone sundial carved in rustic style for an Edinburgh garden

This sundial is delightful. It is the first piece of work by someone in Edinburgh who is learning to do stone carving. It is a very good sundial and they should be proud.

A sundial carved in stone is always special. This sundial is the first piece of work by a stone carver who has begun learning the craft of carving for their own pleasure. The result is very good. The rustic design suits the sunny spot on their slightly overgrown wall in the garden in Edinburgh so well.

Even a rustic design has to follow the sundial rules for the angles of lines on the dial and the angle of slope of the gnomon. Continue reading

The impossible Dihelion sundial photo

The impossible Dihelion sundial photo

We shot this impossible photo blind because there is no room to stand between the sundial and the house wall.

Restoration of the obelisk sundial at Drummond Castle gardens

THE DRUMMOND CASTLE OBELISK SUNDIAL

The sundial consists of 61 multiple dials on raised panels and in sunken hollows. The date of the sundial is 1630. It has been made as an exhibition piece to show all of the sundial mathematics of its era.

The sundial obelisk at Drummond Castle in Perthshire has a long and distinguished history. It has its place in the architecture of the ancient castles and houses in Scotland. It is connected with the very earliest days of the British Sundial Society (BSS). And it is one of the most important free-standing sundials in the British Isles from the early 1600s still surviving.

In 2017 after almost four hundred years outdoors the sundial was showing serious signs of the stone deteriorating. The whole structure was feared to be unsound. Making it safe had become urgent. Continue reading
