A design of azimuth sundial to go in a garden

Azimuth sundial on 10 October at 11.10am

On 10 October the autumn equinox has passed and the cursor reading point has moved out from the inner circle of the dial towards winter solstice at the circumference. The sighting arm carries a short vertical gnomon which casts its shadow in line with the sun.

The azimuth sundial is an intriguing instrument. It finds the time from the direction of the sun. This idea sounds simple, the sun rises in the East, at Noon it is due South, and it sets again in the West, but it is complicated by the time of year. This note is about a new design for a precision azimuth sundial to go in a garden. Continue reading

Armillary sundial on the day of autumn equinox at noon

Armillary sundial on the day of the autumn equinox at noon

Every day at noon the gnomon rod casts its shadow on the centre line of the meridian band. When the day of spring or autumn equinox arrives the two orb balls cast a double shadow onto the meridian band. Away from the equinox, only one orb shadow will show.

Our armillary sundial casts distinctive shadows at noon on the day of autumn equinox, as seen in the photo. Its unique design allows the noon shadow of the gnomon rod to fall on the broad meridian band at its centre line. The two orb balls also cast their noon shadow onto the meridian band.

A modern altitude sundial after Erasmus Habermel

A modern circular altitude sundial after Erasmus Habermel of Prague

Modern reconstruction of a 16th century altitude sundial for studying its mathematics and accuracy. An altitude dial uses the height of the sun to find the time. The dial is double-sided with the two half-years back-to-back.

Erasmus Habermel was a renowned scientific instrument maker working in the court of Emperor Rudolf II in Prague in the 16th century. He made instruments for all disciplines including astronomy and navigation. One of his sundials is an altitude dial in the clocks collection of the Augustine Museum in Freiburg im Bresgau*. It is an elegant circular dial and the mathematical construction is intriguing. Continue reading

North alignment on a Victorian pedestal

Sun direction measured with an angle finder

The direction of the sun measured against one edge of the octagonal stone pedestal using the angle finder and light slit

A Victorian sundial pedestal stands in the gardens of Riccarton estate outside Edinburgh. It once held a beautiful octagonal dial which is now in safe storage. A replacement dial is to go on show and it must be in a correct orientation. The gnomon on a sundial must point north. A wrong alignment will make the sundial inaccurate, and nothing on the 19th century pedestal actually marks the north. Continue reading

A fine 18th century horizontal sundial stands in the gardens of the House of Dun near Montrose. The dial is octagonal made in bronze set in a carved and moulded stone raised on a baluster pedestal and stone step. Elegant tracery scroll work supports the gnomon.

The dial engraving is detailed employing delicacy of variation in deep and light incisions and ornament. The chapter ring carries exact time divisions down to a single minute. Continue reading

Wall sundial at Royal Square in St Helier, Jersey

Wall sundial at St Helier, Jersey

Wall sundial in Royal Square at St Helier, Jersey, Latitude 49.1839° N, Longitude 2.1057° W. The inscription reads: REGULATE YOUR CLOCKS BY THE SUN DIAL. CORRECTION MUST BE MADE FOR THE EQUATION OF TIME WHICH IS GIVEN IN ALL THE ALMANACKS.

This beautiful sundial is set into the wall of the old Picket House in Royal Square, St Helier, Jersey. Historical records show it was made by a talented Jerseyman called Elias Le Gros in the 1820s. In spite of being plastered over at one time by the military authorities and then restored again in 1875 after a public outcry over the dial’s obliteration, it is now in excellent condition, as our photo shows. Our host for lunch that day told us: “The dial is much admired but of course it isn’t accurate.” Poor old Elias Le Gros, now was the time to rescue his reputation! Continue reading

Skein of geese art installation at RSPB Loch Lomond

Skein of geese art installation at RSPB Loch Lomond

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

Our new address and a sundial in the garden

New address and sundial in the garden

A sundial already standing in the garden at our new address for Macmillan Hunter Sundials

Macmillan Hunter Sundials has been in business for twelve years. Until March this year we were at 3 Peel Terrace in Edinburgh, and now we have moved. Our new address is only a mile away at 37 Alnwickhill Road. This property has excellent accommodation and ample working space. When we first came, we did not expect to find a sundial already standing in the garden, and this was a pleasant surprise. On inspection it even proves to have been installed on the correct north-south line to read the time.

The Sandford Fleming sundial memorial nears completion

The Sandford Fleming sundial memorial nears completion

The Sandford Fleming sundial memorial nears completion now the paving is laid. The memorial is on Kirkcaldy waterfront at the end of the High Street.

The Sandford Fleming sundial memorial nears its final phase of completion. The bonded resin paving surface has now been laid. Its creamy colour sets off the brown Corten weathering steel of the sundial extremely well, and it frames the oval shape, which represents Sandford Fleming’s main idea of a system of time that embraces the whole of the world. The sundial is furnished with brief text panels for explanation, and a new information board is on its way.

Sundial memorial to Sir Sandford Fleming in Kirkcaldy

Sundial memorial to Sir Sandford Fleming

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
