9.36  EARLY SUN DIAL.  Authentic 18th century wooden diptych sundial made for the European market.  This precision scientific device is made of an indigenous hardwood in 2 leaves like a book, hence the name “diptych.”  The upper leaf is decorated with a sunburst, 2 flowers and a foliate design, all within a double circle.  It contains a small pendulum bob on a string designed to show the unit level while in use.  The bottom leaf contains a small compass under glass.  The paper compass rose is engraved with the North pointing fleur-de-lis at about the 11 o’clock position, indicative of magnetic North in Europe during the late 18th and early 19th centuries.  The East point is also decorated, indicative of that time period.  The rose is marked in single points of the compass (32 in all).  It is swept by its highly responsive compass needle with brass pivot.  The string gnomon attaches to the upper and lower leaves.  When properly oriented to North, the gnomon casts its shadow on the time of day indicated on the periphery of the compass, as stamped into the tablet -- 5 in the morning to 12, to 5 in the evening.  The front of the tablet is stamped “AUTOR.”  The top is deeply incised with the initials “J.S.”  It is also marked “VERDACE illegible SUPERIOR (?)”  Two small wire hooks and eyes hold the device open or closed.  3 inches long by 2 inches wide and 1 inch thick when closed.  A very charming complete, functional scientific instrument over 200 years old!  495

9.33 COMPENDIUM.   Remarkable 19th century gentleman’s pocket compendium comprising 4 functions in one instrument!  Barometer – altimeter – compass – thermometer.  The aneroid barometer function features a silvered brass dial indicating atmospheric pressure with a huge range spanning 18 to 31 inches calibrated in whole inches divided down to 5/100ths.  It is marked “RAIN, CHANGE and FAIR.”  A delicate indicator needle points the reading.  The dial is signed “Henry Kahn & Co. SAN FRANCISCO, Compensated.”  The altimeter is embodied in the rotating rim surrounding the dial.  The elevation is marked from 0 through an astounding 15,000 feet subdivided in 50 foot increments!  The back of the instrument contains two more functions.  A circular mercury thermometer which indicates the range of degrees Fahrenheit from 8 to 150.  It is marked “FAHT” at the bottom of the dial next to the adjustment screw for setting the barometer.  In the center is the magnetic compass under beveled glass.  It indicates the standard 32 compass points on its mother-of-pearl card with the Cardinal and Intercardinal points identified.  North is designated by a star above a lyre.  The body of the instrument is gilt washed brass with a small pivoting suspension loop at the top.  The rim of the altimeter is knurled for ease of setting the reading.  The entire instrument is 2 inches in diameter and 7/8 inches thick.  With the loop it measures 2 ¾ inches in length.  Outstanding original condition showing careful use.  ALL functions operate properly.  795

According to Kornelia Takacs in her comprehensive reference book ”Compass Chronicles,” 2010, Schiffer Books, Atglen, Pennsylvania, this compass was made in accordance with Samuel Barry Singer’s 1861 patent.  The dry card dial is distinctively marked in half-black, half-white, providing a sharp contrast which was much easier to see in low light.  A nearly identical compass dial is shown on page 42, dated at circa 1868.  Two similar examples are shown, dating 1870 and 1880 respectively (p. 44).

Of particular note is the fact that this American instrument, circa 1880, was designed to measure altitudes exceeding the tallest mountain in the United States at the time, that being California’s Mount Whitney at 14,505 feet of elevation.   Long before air travel!

9.29  RENAISSANCE DIVIDERS.  Super rare, genuine cartographer’s and/or architect’s dividers from the late 1600’s  This museum piece is made of hand-finished cast iron featuring a splined joint at the apex and subtle decorative embellishments along the limbs.  The tips are no longer sharp from centuries of use.  Yet, the action is still very tight and smooth, opening to a width of 4 ½ inches.  4 3/8 inches long.  Amazing original condition for such a working instrument over 350 years old!   WAS $499 NOW! 249

From a major Pennsylvania collection of scientific instrument begun in the early 1960’s.
The accompanying plate is taken from page 34 of  Maya Hambly’s ground breaking reference book entitled “Drawing Instruments 1580-1980,” 1988, Sotheby’s Publications, Philip Wilson Publishers, Ltd., London.  The caption reads “Engraved plate dated 1599 from Giovanni Pomodoro’s Geometria Practtica showing a selection of mathematical instruments.  Museo di Storia della Scienze, Florence, Italy.”  The dividers, top center, identified as “Compafso Hordmario” are nearly identical to the pair offered here. Interestingly, in her comprehensive book, Ms. Hambly offers no known examples of dividers dating earlier than the mid-18th century!

The famed Dutch Renaissance painter Johannes Vermeer painted a portrait in 1668 entitled “The Cartographer,” which depicts a gentleman using such a divider on a map with a world globe in the background.

9.28  3-LEGGED DIVIDERS.  Rare, original set of 3-legged dividers as used by mariners and cartographers in the 1800’s and earlier.  This superb set is unsigned but is likely of German or English origin.  It is absolutely the finest quality ever made.  The body is German silver (non-metallic) with polished steel tips.  The apex of the 3 limbs is a complicated pivot.  Two are like a regular pair of hand dividers with splined joints opening and closing in a straight line.  The addition of a third limb connected by a ball and socket allows the instrument to describe a multidirectional plane necessary in measuring the curvature of a globe.  The quality of its precision cannot be overstated.  The joints are smooth, tight and beautifully-finished.  Speaking to its age, the ball joint has a small washer with 2 telltale holes for tightening, rather than a screw slot.  Such a feature is indicative of 19th century and earlier manufacture.  In addition, the instrument has a double knurled thumb screw which, when tightened, locks all three prongs in position.  A wonderfully clever complication. 5 ¼ inches long by 1 ¼ inches wide at the pivots.  Fabulous original condition.  The best!  349

9.27  AMERICAN POCKET COMPASS.   Turn-of-the-century traveler’s pocket compass constructed in 2 leaves of wood hinged together.  Known as a “diptych” compass, this device has a silvered brass compass in 2 tiers.  The bottom is engraved with the cardinal points of the compass with a star denoting north.  It is signed “W. & L.E. Gurley Troy.N.Y. ”The upper tier is marked in single degrees running counterclockwise from 0 at north to 359 marked in 10’s.  The high quality compass needle has a jeweled pivot and is balanced for accuracy on the southern limb.  A high quality caging device locks the needle in place automatically when the lid is closed.  A “Lubbers line” is scribed in the lid for sighting.  The lid fits snugly on its two hinges and is held by a small pivoting hook.  Outstanding original condition.  The compass is lively and extremely accurate.  279

W. & L.E. Gurley are perhaps the best known surveying instrument makers in American history.  The Gurley name goes back as far as Ephrain Gurley who in 1813 started an iron foundry in Troy, New York.  In 1851 Lewis Gurley began a partnership with his brother William.  In 1852 they founded the company of W. & L. E. Gurley, not far from where their uncle Ephrain began his work.  They advertised as manufacturers of compasses, theodolites, leveling instruments and “apparatus to illustrate the principles of Philosophy.”  A fire destroyed their workshop in 1862, but it was quickly rebuilt that same year.  Both men were active in the civic activities in their community.  William Frank Gurley, son of Lewis began his work in 1882.  He became a partner of W. & L.E. Gurley upon the death of his uncle in 1887.  The company was incorporated under the name of “W. & L.E Gurley” on October 18, 1899.  William Frank died in 1915, but the company carried on under the same name to this day.  (Charles E. Smart, “The Makers of Surveying Instruments in America Since 1700,” 1962, Regal Art Press, Troy, New York).

9.21 MARCHING COMPASS. Very high quality pocket compass made for the American Corps of Engineers for World War I. According to Kronelia Takacs in her monumental reference work “Compass Chronicles,” 2010 Schiffer Publishing, Atglen, PA, pages 73 - 74, a number of British firms manufactured military compasses in WWI. The most widely used was the Verner’s Pattern prismatic compass, Mark VI, made as early as 1905. The dial has 2 scales. The inner area is graduated every 5o, numbered every 20o. The numbers on the outer edge are reversed to be read through the prism and they start form South towards West. The edge of the dial is marked every 1o. North is indicated by a prominent arrow running from the center. The high quality pivot is jeweled. This all brass compass has a hinged lid with glazed port and line of sight. When the lid is opened a clever prong engages the compass’ caging device freeing the card. The pivoting prism can then be move into position to sight the target through the glazed lid while simultaneously reading the compass bearing! The surroundings sides of this complicated device is marked in 5o increments numbered by 10’s 0 through 34 and in ½ points of the compass rose with the cardinal, intercardinal and subcardinal points of the compass identified. The top face of the compass body is marked “ENGINEER CORPS U.S.” The bottom is backed with a rubber insulator and is marked “C.E. (Corps of Engineers) 1918” with the serial number. The top has a pivoting brass suspension loop. This precision instrument comes in its original leather carrying case with closure. The case has a belt loop for attachment. The compass body is 2 ¼ inches in diameter. The case measures 3 ¾ x 2 ½ x 1 ¼. Remarkable original condition. 249

9.17  PRECISION PROTRACTOR. Unique antique protractor hand-inscribed from 0 to 180 degrees left and right.  This amazing device is made of sheet copper – very unusual in that virtually all such instruments of its type were made of brass.  This is probably because copper, an elemental metal, is very malleable and easily worked while being less susceptible to corrosion.  This complicated protractor has no less than 20 semi-circular bands radiating from its center.  The outer most band on the periphery is calibrated in single degrees marked by 10's in a counterclockwise direction.  The next band is marked in 5 degree increments running clockwise.  There are two more bands towards  the center each calibrated in single degrees, 0 centered, marked by 10's, running 90 degrees left and right.  At the locus, marked by a very tiny indent, the lines are so finely concentrated as to be the width of a human hair!  This early instrument likely dates to the late 1700's and was probably not made by a professional scientific instrument maker, but rather a skilled ship's navigator or carpenter.  11 ¾ inches wide by 5 7/8 inches high and less than 1/16 inch thick.  Excellent original condition showing great age and use, but no abuse.  A true rarity!  475

This genuine scientific instrument has a surprising array of multiple features. It is two–tiered. There is a magnetic compass showing direction on the upper scale of the silvered brass dial calibrated in single degrees from 0 to 360 marked by 10's. The compass needle has an agate pivot, indicative of its quality. The lower tier on the Western edge is marked in degrees of declination in single degree increments starting with 90 at North, then 0 at West increasing again to 90 South.  The scale is overlaid by a very fine brass inclinometer which indicates single degrees. Yet a third function is the ability to sight a bearing using the 2 folding sighting vanes in blackened brass finish on the North and South sectors. The brass was blackened to negate the effects of the sun's glare.  For carrying, the compass is equipped with a compass needle caging device at the East point. For determining inclination there is a flat bar attached to compass body on the West end for alignment with the surface being measured.  Although unmarked this precision instrument is undoubtedly French.

9.97/13.91  BUTTERFIELD SUN DIAL.  An astounding offering!  This is a late 16th or very early 17th century cased pocket sun dial of the type known as a Butterfield dial, invented by Britisher turned Frenchman Michael Butterfield circa 1690.  This stunning surviving example is all brass made by "LeMaire Fils, Paris" as beautifully-engraved just below the compass.  The very early form compass needle rides over the engraved compass rose indicating the cardinal and intercardinal points of the compass marked N, S, and O, with the north point indicated by a fleur-de-lis.  The dial is constructed with a hinged gnomon, the angle of which can be adjusted for latitude as indicated by the beak of a bird on a scale reading from 40 to 60 divided in single degree increments.  The upright gnomon is spring-loaded and will lie flat on the body of dial on either side. The dial plate has 3 beautifully-engraved chapter rings for latitudes of 43, 46, 49, and on the extreme periphery 52 degrees, these encompassing the area between Gibraltar and the Shetland Islands.  The time indications in whole hours are marked in Roman numerals from 4 A.M. to 8 P.M. divided by 15 minute increments.   The reverse of the dial is engraved with at least 23 latitudes of prominent European cities of the time.  Incredibly this superb instrument comes in its original felt-lined wooden case with its durable fish skin cover,  all of which are in a remarkable original state of near pristine  preservation!  The octagonal dial measures 3 ¼ inches long by 2 5/8 inches wide, fitting neatly in its case measuring 3 ½ inches long by 3 inches wide.  The hinged lid of the case closes with a button latch, further secured by 2 hook and eye closures.  A remarkable scientific instrument in unheard of original condition over 300 years old!  Museum quality of the first order. 2879

An identical dial signed "Le Maire Fils A Paris" and dated 1740 is shown on page 146 of Harriet Wynter's and Anthony Turner's landmark reference work "Scientific Instruments," 1975,  Charles Scribner's Sons, New York.  That dial is missing its original case.

Michael Butterfield (1635 - 1724) was a British clockmaker who moved to Paris around 1663.  He worked at the royal court and was appointed chief engineer to King Louis XIV.  He opened a shop selling precision instruments at Rue Neuve-des-Fossés, Saint Germain in 1677.   He sold all forms of sundials.  But his most popular was the small travelling dial with the adjustable gnomon having a bird motif and three chapter rings.  Fashionably it became known as the Butterfield dial.  The basic design of this dial was known prior to Butterfield's design.  But his was quickly embraced and manufactured by other instrument makers in Paris and beyond.  Among Butterfield's famous clients was the Russian Czar Peter the Great, who visited his shop in 1717 and ordered a great quantity of gilt copper dials.

9.96  EARLY AMERICAN PLANETARY MODEL.   Extraordinary, late 19th century orrerey of exceptional size and complexity.  This fascinating depiction of the earth and its planetary neighbors was designed in such a way to accurately depict the earth's motion relative to the sun and moon.  It is otherwise known as a "tellurium" (alternatively "tellurion') from the Latin "tellus" meaning earth.  The ingenious device features a heavily weighted 12-sided base decorated with applied chromolithographed signs of the Zodiac and the names of the associated constellations on its perimeter.  Moving inward are the days of each month, divided into half days marked in 5 day increments.  Then are the boldly marked months.  Next are the points of the compass identified by initials (e.g., WEST, WbSW, WbS, SW, etc.).  Next are the degrees of the compass in 10 degree increments in 4 quadrants.  Finally, the inner degree circle is calibrated in half degrees marked by 5's in alternating black and white squares.  A sculpted, highly polished circular metal stand rests on the base and supports the revolving mechanism as well as the central depiction of the sun.  A metal arrow indicates the precise location of the apparatus relative to the markings on the base.  The sun is represented by a serrated brass arc with a knurled brass rod which points to the Perigee of a corresponding point on the globe.  The rotating arm is decoratively cast in relief with floral designs and the maker's name "ANDREWS."  The arm is 12 ½ inches long and supports the earth with its orbiting moon.  The moon is represented by a solid wood ball painted black and white for day and night.  By means of a complex set of bevel gears and ellipticals the moon slowly rotates as it orbits the earth.  The earth, in turn, rotates around the sun.  The globe is constructed in the traditional way with an 8 inch plaster sphere overlaid by chromolithographed gores depicting the land masses, oceans, countries, major cities, mountain ranges, rivers and other topographical features such as ocean currents and prevailing winds.  A brass arm with arrow pivots from the North Pole extending to the equator, marked in single degrees of latitude.  The globe maker's cartouche in the Indian Ocean reads, "Made By WEBER COSTELLO CO. Chicago Height, Illinois. Copyright by G.W. Bacon & Co., Ltd., London."  A revolving 2-part metal "cage" encompasses the globe but does not rotate with it.  The overall width is 21 inches and the maximum height is 17 inches.  The 12-sided base is 1 foot in diameter.  Overall cosmetic condition is "excellent" with expected toning from age.  Remarkably there is no damage or losses and the apparatus is fully functional. 6500  Special Packaging

9.90 / 22.40  POCKET COMPENDIUM.  Remarkable 2nd half of the 19th century English gentleman’s traveling instrument containing FOUR scientific functions in one!  This compact device is signed in engraved script “L. Braham & Co. 142 Southampton Row LONDON.”  On the front it features 2 functions: a weather barometer and an altimeter.  The barometer function, reading effectively from 28 to 31 inches of atmospheric pressure, is marked “RAIN, CHANGE, and FAIR.”  The scale is calibrated in inches of mercury down to 5/100ths.  The second function, the altimeter, indicates the altitude in feet from sea level to 8000 feet in 50 foot increments marked by thousand’s.  Both are indicated by a very fine needle pointer.  To aid in the reading, the revolving knurled bezel is equipped with a built-in “bubble” magnifier.  The reverse of this amazing instrument has a curved mercury thermometer reading from -5 to 165 degrees Fahrenheit.  Central to the display is a functional compass made on Singer’s Patent.  The high quality card is made of mother of pearl with a central agate pivot.  The compass is marked in single points of the compass with the cardinal and intercardinal points identified.  North is indicated by a lyre symbol.  Remarkably this miniature compass has a caging device operated by a tiny lever to lock the card in place when not in use!  The instrument is solid brass with traces of original gilding.  It has a pivoting suspension loop at the top and a small aperture at the bottom for setting the barometer reading.  A mere 2 inches in diameter and 1 inch thick.  All functions are working and very accurate.  The best of its type we have seen in our 40 years. SOLD

Samuel Barry Singer, a master mariner form Southampton, England patented a unique compass card in 1861.  He intended for his design to be used in ships’ compasses, but the dials were most often used in pocket compasses.  His innovation incorporated a distinctive half black, half white card.  The sharp contrast was designed to make reading easier in low light conditions.  The North half of the dial is black and the South white.  The lyre symbol may have had a metaphorical meaning, representing Vega, known as the Harp Star, one of the brightest stars in the Northern Hemisphere in the constellation of Lyre.

9.76  18th CENTURY ORRERY by FAMOUS MAKERS.  Important, exceptionally rare late 1700’s mechanical model of the solar system made by the famous English scientific instrument makers W. & S. Jones, London as signed in two blocks near the center, “Designed for the NEW PORTABLE ORRIERIES by W. JONES” -- and “Made and fold (sic) by W. & S. JONES 30 Holborn, LONDON,” with each block held by winged angels.  This working apparatus consists of a wooden turntable supported on tripodal feet overlaid with a comprehensive lithographed view of the cosmos from an 18th century perspective.  The central title reads “A TABLE of the principal AFFECTIONS  of the PLANETS Jany 1st 1794 Published as the Act directs by W. & S. Jones.”  Above it is the legend reading “ANNO 1794” listing the planets “MERCURY, VENUS, EARTH MARS, JUPITER, and SATURN” with a table indicating “Mean Distance, Period of revolutions, Diurnal rotations, Diameters and Greatest elongation of planets” for each.  To the left is a table listing SATURN’S Satellites” as held by a scholar sitting next to a globe.  On the right is a table listing “JUPITER’S Satellites” as held by a robed scholar pointing to the table.  Below is a large hemispherical chart depicting the relative positions of the planets from the year 1796 through 1810 entitled “THE SOLAR SYSTEM.”  Encircling these central vignettes (moving outward) are the individual degrees of the compass, followed by 2 bands of sectors, each containing 90 degree quadrants marked by 5’s and running from 0 to 90, then 90 to 0.  Extending outward from them are the cardinal, intercardinal and sub-intercardinal points of the compass.  Next are the 12 signs of the Zodiac with their respective characters charmingly depicted.  Outward from these is an interpolative degree scale divided down to ½ degree in units of 30 degrees each.  Finally the outer periphery is divided into the identified 12 months of the year.  If all of this weren’t amazing enough, the equally fascinating aspect of this mechanism is its geared clockwork depicting the Sun, Mercury, Venus, Earth and its moon.  Through the complex gearing system, operated by an ivory-handled brass crank on the rim, each planet is shown to revolve about the sun.  In addition the earth turns on its axis as the moon revolves around it.  There are 2 engraved brass rings below the earth.  The bottom ring shows the phases of the moon, while the upper ring is divided into 15 degree sectors marked with the traditional signs of the Zodiac.  Charmingly, the Earth is made using traditional chromolithographed paper gores.  The makers’ name “JONES LONDON” appears in the Pacific Ocean.  Simulating day and night, a crescent shaped brass light curtain encircles the Earth while the ivory moon revolves on a tilted plane in keeping with the Tropics of Cancer and Capricorn.  The entire apparatus is in an amazing state of original preservation with obvious signs of age, careful use and minor restoration.  12 5/8 inches in diameter.  Completely functional.  Museum quality of the first order.  Price Request Special Packaging

William Jones II was born in 1762 and began his work as a philosophical, mathematical and scientific instrument maker on Holborn Street, London in 1787.  In 1792 he joined with his brother Samuel in a partnership to form the firm of W. & S. Jones.  That well known, highly respected and very prominent instrument making firm flourished until 1832 at 30 Holborn, London.  They were known to have manufactured and sold planetariums and sun dials among other instruments.  (Gloria Clifton, “Dictionary of British Scientific Instrument Makers 1550-1851,” page 153.)
An identical, later Orrerey is pictured on page 47 of Harriet Wynter and Anthony Turner’s landmark reference book “Scientific Instruments,” Fig. 50, described as “English orrery, signed ‘Designed for the New PORTABLE ORRIRIES by W. Jones and made and sold by W. & S. JONES 30 Holborn, LONDON’,  c. 1810-20, diameter approx 315 mm (12 ½ in).”   The caption reads (verbatim), “Circular base covered with a paper printed round the edge with a zodiac calendar.  Contained within this is the upper half of the circle is ‘A Table of the principal AFFECTIONS of the PLANETS published by W. & S. Jones in 1794,’ showing the distances, periods, sizes, etc. of the planets out to Saturn.  In the lower half of the circle is a pictorial representation of the solar system.  A brass sphere representing the sun is mounted on the central shaft around which revolve the inferior planets represented by ivory spheres, and the earth and moon.  The moon is mounted on a silvered zodiac scale with a silvered dial carrying a lunar phase diagram below.  The whole machine is operated by a turning a cranked handled which is attached to an arbor below the base-board, meshing by an endless screw to a wheel connected to the central shaft of the movement which is carried through the base.”

A virtually identical example of this early orrerey was offered by "Tesseract" of Hastings-on-Hudson, New York as item number 4, in their catalog 64, Winter 1999/2000 for $22,500.

9.02  POCKET SUN DIAL.   Rare, incredibly old sun dial made entirely of ivory with pewter plates and brass fittings.  This amazing relic is of French originand represents what is known as a “Dieppe Magnetic Azimuth or Bloud-type dial.”  It is attributed to the early Parisian dial maker Jacques Senecal and dates circa 1660!  It is of the diptych type, meaning it has two leaves or tablets, hinged in the middle.  The outside top of the upper leaf is equipped with a pewter equinoctial dial for telling time by means of a pin gnomon.  The inner side is fitted with a lunar volvelle, allowing it to be used to determine the time at night when the moon was visible.  The main part of the dial occupies the lower leaf of the diptych.  A recessed bowl accommodates a delicate magnetic needle suspended on a pyramidal brass pivot.  Cleverly, this dial actually represents a form of mechanical computer.  The underside of the leaf holds a rotating disc engraved with the months and days of the year.  It is connected to the interior hour scale below the compass needle which acts as the gnomon.  Rotating the outer disc to the corresponding day moves the hour scale within setting it to the proper “altitude” for the time of year.  A typical horizontal dial with string gnomon is also provided, with the hours engraved in the ivory around the periphery of the compass rose.  In the bottom plate of the dial there is a finely-engraved paper card, the outer edge of which is marked in degrees by tens in four quadrants.  Within is an 8-pointed star with a fleur-de-lis at the North point.  The other star points are marked with the latitudes of important European cities such as “Paris, Venise, Rheims, Roma, Londre,” etc.  It is alsoequipped with a clever pivoting brass “stay” which holds the lid open, fitting neatly into a recessed slot when not in use. This lovely instrument is profusely engraved with decorative pinwheel elements on the periphery of each of its tablets, inside and out.   There are two very early pewter repairs in the lid to stabilize an age crack, and the very tip of one of the tiny brass hooks is off.  Otherwise this 350 year old instrument is in amazing condition for its age.  A museum piece!  SOLD

 Literature:  Hester Higton, “Sundials, An Illustrated History,” 2001, Philip Wilson Publishers, Ltd., London.  Page 89 depicts a very similardial described as, “Dieppe magnetic azimuth dial by Jacques Senecal, c. 1660.  The inside of this dial has a lunar vovelle in the upper leaf and the main dialset into the lower one.  Collection of the National Maritime Museum, London.”

9.03  ARMILLARY SPHERE.  Rare early 19th century model of the solar system made by the famous French globe maker Delamarche as printed on the terrestrial globe in the center.  This planetary model is based on the Ptolemaic system devised by early Greek astronomer Claudius Ptolemaeus (A.D. 90 – 128) in which he envisioned the solar system as a set of nested spheres.  Ptolemy’s model depicted the Earth at the center of the solar system, whereas the later (and correct) Copernican system was sun-centered.  This exceptional example features a pewter equatorial ring engraved in single degrees, 0 – 360.  It is supported on a cast iron strut which also houses the brass Meridian ring divided into quadrants of 90 degrees each.  As mounted, the Meridian ring is free to revolve and thus indicates the sun’s declination at any time of the year.  The broad diagonal paper ring is beautifully engraved with the signs of the Zodiac.  The remaining horizontal rings indicate the north and south tropics and the equator.  This especially fine model is in a marvelous state of  preservation, considering the fact that it is over 200 years old!  Museum Quality.   

 The first maker to produce globes in France for use by the general public was Charles-Francois Delamarche (1740-1817).  Delamarche’s workshop was on Rue du Foin, St. Jacques au College Me. Gervais’, Quartier Latin.  Subsequently his addresses were Rue du Jardinet, then  No. 7 Rue du Battour, all Paris.  Likely this sphere is the work of his son and successor, Felix.

The term Armillary sphere comes from the Latin armilla meaning hoop or bracelet.   The earth is shown as a small globe in the center of the sphere which is formed by 2 rings at right angles.  The tropics of Cancer and Capricorn (representing the sun’s maximum North and South declinations from the Equator) and the Arctic and Antarctic circles are represented by narrower rings.  A broad ring crossing the tropic rings represents the ecliptic or path of the sun.  The sphere is mounted within a Meridain ring set into the Equatorial ring.  Practical use of the Armillary sphere as a solar system teaching aid was superseded by the Orrery in the early 18th century.  (A. Major, Maritime Antiques, 1981, Tantivy Press, London).
