Looking for a place for our armillary sundial

Looking for a place for our armillary sundial

The armillary sundial captures the dynamics of the earth spinning on its axis and orbiting the sun. The equatorial band is pierced with markers for the hours. A meridian band shows the seasons.

Now that we have moved, we have been looking for a place for our armillary sundial. Before, it was nestling gently in its surroundings with plants in the garden growing up through the rings and wrapping themselves around. For the moment it is out in the open where  we can see it better. It has an air of almost floating on its stand with the lightness of the rings and the delicate shadows on the ground.

A sundial commission unwrapped for an 80th birthday celebration

A sundial commission for an 80th birthday celebration

The design is a polar sundial, which tilts up at the latitude angle. The happy owner has unwrapped his 80th birthday present from the family.

“My father turns 80 this year and we are looking to commission a sundial in celebration. Is this possible? What’s the process? How long does it take?” When this email appeared in our inbox one day in March of course we wanted to follow it up. It sounded such a lovely suggestion from the family. Later when we learned a little more it looked like a perfect plan. Continue reading

Armillary sundial reads summer solstice by the shadow of a ball at noon

At the summer solstice the armillary sundial casts a shadow of the ball at noon

At summer solstice the ball on the upper tropic ring casts its shadow exactly onto the opposite ring below. The upper tropical ring is the tropic of Cancer and lower ring is Capricorn.

The armillary sphere dates back to ancient times when astronomers created their own vision of the earth and the heavens. The idea still works today and our own design creates a sundial with a special feature of two balls that mark the passage of the seasons by their shadows. One of the balls reads summer solstice. This is the high point of the year when the sun is highest in the sky. Continue reading

Armillary sundial shadow one month on from winter solstice

Armillary sundial shadow one month on from winter solstice

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

An armillary sundial in early morning

An armillary sundial in early morning

This is our new sundial design. It stands in our garden among the plants. It is early morning and the sun has just reached the centre band where you read the time.

An armillary sundial has a wonderful form. It has mathematical rings creating beautiful shapes with circles and lines. The sundial in the photo has just begun to catch the early morning sun in the garden.

The sundial gnomon is the slanting rod in the centre of the rings, and the wide sweeping band is where you can read the time. These features are the same as other armillaries, but our design has special secrets. Continue reading

Time lapse study of shadows and how a sundial reads the time

Time lapse on precision of a sundial

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
