Indian Planispheric Astrolabe Inscribed in Sanskrit
Collection: National Museum of American History
Object type: astrolabe
date made: 1805
Physical Description: brass (overall material)
Measurements: overall: 28.5 cm x 14 cm x 4.8 cm; 11 7/32 in x 5 1/2 in x 1 7/8 in
Credit line: Gift of Ed Nagel
Description: The astrolabe is an astronomical calculating device used from ancient times into the nineteenth century. Measuring the height of a star using the alidade on the back of the instrument, and knowing the latitude, one could find the time of night and the position of other stars. The openwork piece on the front, called the rete, is a star map of the northern sky. Pointers on the rete correspond to stars; the outermost circle is the Tropic of Capricorn, and the circle that is off-center represents the zodiac, the apparent annual motion of the sun. Engraved plates that fit below the rete have scales of altitude and azimuth (arc of the horizon) for specific latitudes. This brass Sanskrit astrolabe has a body with throne, handle, ring, alidade with sighting tube and pin, rete, eight plates, and a wedge at the front that holds the instrument together. The instrument is signed Virabha (Vitrabhadra).

Portable Diptych Sundial by T. G. Kleininger
Collection: National Museum of American History
Object type: sundial, horizontal portable
sundial
Date made: 1790s?
maker: Kleininger, Johann G.
Measurements: overall: 1.5 cm x 4.5 cm x 8 cm; 19/32 in x 1 25/32 in x 3 5/32 in
Topics: Science

Description: This rectangular wooden diptych sundial has paper scales and tables with black ink and green and red coloring. A brass hook and eye hold the sundial open for use; a hook for keeping the dial closed is missing. Leaf 1a is a latitude table for 36 European and American cities (a complete list is in the accession file). Leaf 1b contains holes for latitudes of 40, 42, 44, 46, 48, 50, 52, 54, and 56 degrees, although only the holes 46-52 are drilled completely through the leaf and therefore functional. A string gnomon is tied loosely at 46 degrees. Leaf 1b also contains an equinoctial sundial calibrated from VII to XII to V by units with lines at the half-hour points. Leaf 2a contains a horizontal sundial calibrated from 4 to 12 to 8 by units with divisions for each fifteen-minute interval. Inset in the inside of this face is compass with a rose of four labeled cardinal points. The compass is offset roughly ten degrees west for magnetic variation. The compass glass and needle are missing. Leaves 1b and 2a are decorated with flowers and garlands of leaves. A mark reads: J. G. Kleininger. fec.
Johann G. Kleininger (1763-1824) made diptych and cube dials in Germany Related dials reportedly have initials reported variously as J. G. (Adler Planetarium), I. G. (National Maritime Museum, Greenwich; Whipple Museum), and J. P. (Museum of the History of Science, Oxford - this is probably his son Johann P. Kleininger). The latitude table and compass directions on this dial mix German, French, and English terms (for example: Nord, Ost, Sud, West). Note also that Washington, D.C., is listed, suggesting the date given.

Description: This brass Gunter-type horary quadrant has one brass sight on the top of the quadrant along one radius. There is no pinhole in this sight; it is completely solid. It appears that there was never a second sight. The plumb-bob and string which belong at the vertex are missing. The quadrant contains a geometric square marked from 10 to 50 to 10 in units of one degree, an hour arc (U-shaped) from I to VI to XI to XII and an azimuth arc from 30 to 90 to 120 by ten degrees, an ecliptic arc calibrated by zodiac symbol, a declination scale to 24 degrees, a horizon arc marked from 10 to 30, a second hour arc marked from VIII to I, a calendar arch lettered by month, and a circumference marked from 0 to 90 in units of one-half degree. There are suns between most Roman numerals on the hour arcs, moons on each side of the calendar arch, and sets of three dots at each 5-degree mark on the circumference. Five stars are charted: VH, BE, LH, A, PW. This dial was made for a latitude of approximately 52 degrees. There is no instrument maker with initials T. D. who worked around 1790 in Clifton, or in the inventory of the National Maritime Museum, Greenwich.

 "Machine Sûre & commode pour tirer des Silhouettes.\nVoici le caractère que j'assignerois à la Silhouette de cette jeune personne. J'y trouve de la bonté Sans beaucoup de finesse; de la clarté dans les idées, & le talent de les concevoir avec facilité; un esprit fort industrieux, mais qui n'est point dominé par une imagination bien vive, & qui ne s'attache guère à une exactitude scrupuleuse. On ne retrouve point dans la copie le caractère de gaieté qu'annonce l'Original; mais le nez a gagné dans la silhouette - il y exprime plus de finesse."]
