This decorative globe stands out by the many constellations engraved on it. From the beginning of the sixteenth century, European globe makers as well as astronomers strove to populate the heavens with new constellations in addition to the 48 Ptolemaic ones transmitted from antiquity. By 1800 the number of constellations had more than doubled and the sky had become so crowded with them that the other astronomers started complaining about their usefulness. This has ultimately resulted in international standards for dividing the sky into constellation areas. Many constellations invented in the course of time and duly engraved on this silver globe have since disappeared and are unknown today. Like the classical ones, each of the new constellations has its own history. For example, the introduction of the French invention of the hot air balloon as a constellation was proposed by Lalande in 1798 during the first astronomical congress on the Seeberg near Gotha. After some discussion the constellation was accepted, however, on the condition put forward by Bode, that the German invention of the printing press by Johann Gutenburg should also be honoured by a new constellation. The constellations have not been placed at random, but their order is occasionally disturbed. This is the case for instance for Ursa Minor and Draco around the North Pole. The style of the constellations is to some extent influenced by the artist or engraver. The best example is the bull which looks more like a wild boar. There is only one balloon, the other balloon like feature is the distorted image of Reticulum which was originally intended by Lacaille as a pair of cross wires (in French reticule) but is here presented as a hairnet
