The meridian ring and zodiac in engraved brass and the rest in papier mache. Constructed of pasteboard covered with hand-coloured paper. Equator, polar and tropic circles, and celestial equator with graduations on the outer side with divisions for months and houses of the zodiac. Ebonised turned wood stand. Width 23 cm, height 33 cm.
Very few armillary spheres have been made in a combination of brass and papier maché. Some wear and chipping to rings of papier maché, wood stand with one repair.

In the centre a globe 4,5 in diameter with cartouche in Spanish reading: "Globo terrestre / por / F Paluzie / Barcelona". Two movable brass arms with sun and moon discs.

ARMILLA, Armil or Armillary Sphere (from the Lat. armilla, a bracelet), an instrument used in astronomy. In its simplest form, consisting of a ring fixed in the plane of the equator, the armilla is one of the most ancient of astronomical instruments. Slightly developed, it was crossed by another ring fixed in the plane of the meridian. The first was an equinoctial, the second a solstitial armilla. Shadows were used as indices of the sun´s position, in combination with angular divisions. When several rings or circles were combined representing the great circles of the heavens, the instrument became an armillary sphere. Armillae are said to have been in early use in China. Eratosthenes (276-196 B.C.) used most probably a solstitial armilla for measuring the obliquity of the ecliptic. Hipparchus (160-125 B.C.) probably used an armillary sphere of four rings. Ptolemy ( c. A.D. 107-161) describes his instrument in the Syntaxis (book v. chap, i.), and it is of great interest as an example of the armillary sphere passing into the spherical astrolabe. It consisted of a graduated circle inside which another could slide, carrying two small tubes diametrically opposite, the instrument being kept vertical by a plumb-line. 
No material advance was made on Ptolemy´s instrument until Tycho Brahe, whose elaborate armillary spheres passing into astrolabes are figured in his Astronomiae Instauratae Mechanica. 576 The armillary sphere survives as useful for teaching, and may be described as a skeleton celestial globe, the series of rings representing the great circles of the heavens, and revolving on an axis within a horizon. With the earth as centre such a sphere is known as Ptolemaic, with the sun as centre, as Copernican. (Higgins - Chisholm, Encyclopaedia Britannica, 1911).
