A rare Italian portable pillar sundial Initialled with maker's monogram I. A. G A rare Italian portable pillar sundial Initialled with maker's monogram I. A. G. A. F., dated 1778 The removable gilt ogee moulded cap with ball-shaped finial and internal plunger concealing two hinged brass gnomons over cylindrical shaft applied with printed paper scale annotated with calendar to upper edge with months annotated in Italian, over two opposing projected scales delineated with two sets of curved hour scales annotated with opposing Arabic and Roman numerals V-XII and 7-1 each scale with printed banner beneath, one annotated ESPOSTO IN FACCIA AL SOL, I. A. G. A. F. 1778 the other SEGNO LE ORE, elev. Pol. 45. the lower margins further inscribed in Italian to instruct which of the two gnomons should be used for each scale, on heavy crisply-turned cast gilt brass base, 16.5cm (6.5ins) high; with a brass cylindrical case applied with reinforcement strips to exterior. Provenance: The beneficiaries of the Estate of an Italian connoisseur collector of horological artefacts and works of art. Column or pillar sundials (sometimes termed shepherd's dials) are a type of altitude sundial probably developed during the early Renaissance. Indeed similar pillar sundials to the current lot were certainly in use well before the 1530's and feature in Hans Holbein's works 'The Ambassadors' and portrait of Nicholas Kratzer. The current lot is designed to operate at 45 degrees latitude and is used by first removing the cap and to fold-out the brass gnomons. The cap then needs to be re-inserted ensuring that the gnomons line up with the relevant date printed to the upper margin of the shaft. The instrument then needs to be placed in sunlight and aligned so that the shadow of the gnomon falls vertically down the column, the time will then be indicated at the point where the shadow terminates on the projected hour scale printed beneath. As the sundial relies on the altitude of the sun to provide a reading the hour scales are annotated with two opposing sets of numbers (one in Arabic numerals the other Roman) these allow the time to be ascertained both in the morning or afternoon and converge at six o'clock.

A fine French brass horizontal compass sundial Michael Butterfield, Paris A fine French brass horizontal compass sundial Michael Butterfield, Paris, circa 1700 The square baseplate signed Butterfield, AParis to lower edge and incorporating a compass centred with a finely engraved thirty-two point rose fully annotated in French within glazed moulded bezel divided into 360 degrees with scale annotated for every ten degrees both for the entire circumference and for each quarter to the inside edge, the circular sundial plate fitting via overlapping friction collar onto the compass with repeat signature Butterfield AParis and scroll-bordered aperture revealing section of compass scale opposing hinged bird engraved adjustable gnomon calibrated in degrees for elevation, the circumference with four hour scales for 52, 49, 46 and 43 degrees annotated from the outside in for hours 4-12-8, IIII-XII-VIII, 4-12-8 and V-XI-I-VII divided into half hours with cruciform half hour markers, the centre engraved with latitudes for twenty-two cities including Londres 51..32, Hambourg 53..41, Strasbourg 44..42, Nantes 47..46, Grenoble 45..13t, Marseille 43..20 and Nice 43..32 , the baseplate 9cm (3ins) square. Provenance: The beneficiaries of the Estate of an Italian connoisseur collector of horological artefacts and works of art. Michael Butterfield was an English Instrument maker born in 1635 who is believed to have emigrated to Paris in around 1663. Butterfield initially set up business in rue Neuve-des-Fosses, faubourg Saint-Germaine trading under the sign 'AUX ARMES D'ANGLETERRE' (at the sign of the English coat of arms) however by 1685 he had relocated to a workshop in 'Le Quay de l'Horloge'. Amongst Butterfield's patrons was the Royal Court and in 1717 he supplied a number of instruments to Tsar Peter the Great. He died in 1724 Butterfield is best known for devising a pattern of pocket sundial with compass set into stretched octagonal plate often annotated with several hour scales for differing latitudes and fitted with a hinged gnomen with adjustable vane calibrated in degrees (see lot XX for an example by N. Bion). In addition to sundials Michael Butterfield also well known for producing fine quality sectors and related drawing and surveying instruments. The current lot is notable in that it is clearly made with accuracy in mind hence would have been an expensive 'top of the range' model when made. The extensively annotated rose and the finely divided outer scale to the compass allows accurate direction readings to be taken. In addition to this the sundial itself is engraved with four hour chapters, and relevant latitudes for each European city in the centre includes annotations for seconds as well as minutes. The present dial can be compared to a compass sundial attributed to Pierre Le Maire, Paris sold at Sotheby's, New York MASTERPIECES FROM THE TIME MUSEUM, PART FOUR, October 13th and 14th, 2004 (lot 773). This example is of the same basic form as the current lot with compass set beneath the sundial plate visible through a shaped aperture in front of the gnomen. However it varies in that there is only one hour chapter which is compensated by the fact that the plate itself is hinged allowing an inclined plane dial (rather than relying on several hour chapters annotated for differing latitudes engraved on a fixed as per the current lot).

A French brass Butterfield pattern portable horizontal compass sundial... A French brass Butterfield pattern portable horizontal compass sundial Nicholas Bion, Paris, early 18th century The elongated octagonal plate with four hour scales for 55, 50, 45 and 40 degrees, the outer 4-12-8 divided into quarter-hours, the next three IIII-XI-I-VIII, 4-12-8 and IIII-XI-I-VIII divided into half hours with wheatear half hour markers for the Roman numeral chapters, the centre with foliate engraved panel within band signed N. Bion, A Paris , with glazed four-point compass and hinged bird engraved adjustable gnomen calibrated in degrees for elevation to the outer edge, the underside engraved with latitudes for twenty cities including Londres, Geneue, Cologne, Milan, Madrit, Metz, Turin and Paris , 7.1cm (2.8ins) long; in original leather case with red velvet lined interior, 8.5 (3.35ins) long overall. Provenance: The beneficiaries of the Estate of an Italian connoisseur collector of horological artefacts and works of art. Nicholas Bion was born in 1652 and is believed to have been active as an instrument maker from around 1680. A trade card pronouncing him as 'Ingenieur du Roi' and listing his address as 'le quay d'Orledge du Palais au quart de Cercle' exists in the collection of the Cluny Museum Paris. In 1709 Bion published TRAITE DE LA CONSTRUCTION ET DES PRINCEPAUX DE USAGE DES INSTRUMENS DE MATHEMATIQUE within which (page 362) he included an engraved image of an instrument almost identical to the current lot. Bion is believed to have worked well into the 18th century and died in 1733. This type of portable pocket sundial was devised by Michael Butterfield, an English Instrument maker who settled in Paris around 1685. By the end of the century Butterfield's workshop was also located on the 'Le Quay de l'Horloge' hence he would have known Nicholas Bion as a neighbour.
