Very Large Early Nineteenth Century Sun Dial by Adie & Son Edinburgh

For sale, a very large early Nineteenth Century Sun Dial by Adie & Son, Edinburgh.

This unusually large fifteen and a half inch circular dial plate is engraved around the circumference with large Roman numeral hour markings and parchment scroll motifs at either end, it also has an accompanying smaller minute scale around the outer edge. To the centre is a beautifully engraved, eight-pointed compass rose with an intricate star pattern emanating from the centre. It is bordered by a number of concentrically engraved circles providing a method for managing the variations between sun dial readings and clock or watch readings at various times of year. They include month, time adjustments and an indication at the various points when the timepiece should be reading faster or slower than the sun dial. All of the above are encircled by a ring with an engraved dart motif and then finished on the outer edge with the various markings for the eight points of the compass.

A solid brass gnomon is positioned over the top in the North, South position and the Southern most edge of the plate is engraved with the name of the renowned Scottish scientific instrument making business of Adie & Son, Edinburgh.

A rare large format and complex sun dial by one of the most respected makers of the early Nineteenth Century.

The history of the firm, Adie & Son began in 1776 with the celebrated Edinburgh scientific instrument maker John Miller, the uncle of Alexander Adie. Miller himself had been apprenticed under the world-renowned maker George Adams so Alexander was privileged to have had an uncle from such a prestigious background.

From 1789, Adie (1774 – 1858) undertook his apprenticeship with Miller and by 1804, a partnership was agreed which traded at various addresses on Nicholson Street. Miller & Adie continued to trade until 1822 (although Miller had died by 1815) whereafter the business was renamed solely to Alexander Adie. By this point, Adie was himself an accomplished maker with a focus on meteorological instruments and had by 1818 taken out a patent (No: 4323) for a sympiesometer, a type of barometer designed initially for marine use which contained hydrogen and almond oil instead of mercury. Perhaps the most well-known instrument that the Adie family are now recognised for, this invention was patented as, “An improvement on the air barometer” an instrument that had been conceived as early as 1668 by Robert Hooke but never brought into practical use until Adie’s later developments.

By 1822, Adie had a family of three sons, John (1805-1857), Richard (1810-1881) and Patrick (1821-1886) and it is sensible to presume that all undertook some kind of apprenticeship under him. The eldest, John went into business with his Father to form Adie & Son in 1835 and Richard is also known to have worked for the firm. Like many scientific instrument making firms of the period, both Richard and Patrick were to go on to set up their own successful satellite firms under their own names both in Liverpool and London respectively.

In Edinburgh, the partnership between Alexander and John continued to grow, they received Royal Appointments from both William IV and Queen Victoria and were the only two instrument makers elected as Fellows of The Royal Society of Edinburgh. The links with the Society are considered to be the reason for their commission to build William Wallace’s patent Eidograph, an improvement to the less accurate pantograph. They had trading links with Spencer, Browning & Rust (they retailed Adie’s Sympiesometer) and John completed the installation of a Troughton & Simms altazimuth circle for The Edinburgh Astronomical Institution at Calton Hill Observatory after Simms proclaimed himself too busy to undertake the exercise! They were also known to have had links with Charles Darwin.

Sadly, John shot himself in 1857 after suffering fro
