We are likewise informed that in the National Museum’s collections may be found a celestial globe which is attributed to Petrus Theodorus. It is of gilded brass, having a diameter of 24 cm., and while undated presumably is of the last quarter of the seventeenth century. The globe ball is supported by a bronze figure of Atlas, the whole standing 86 cm. in height. Tycho Brahe is the accredited authority for the representation of the several fixed stars. Erhard Weigel (1625-1699)[65] has place among the globe makers of the period as one who sought to reform, and, in some measure, to popularize both astronomical and geographical science, particularly the former, applying his own inventive ability to that end in the matter of globe construction. In this he appears to have been rather more ingenious than practical. He seems to have achieved special distinction in his day as theologian, philosopher, astrologer, and mathematician. Weigel was a native of the Rhenish Palatinate. Under many difficulties, on account of the poverty of the family, he acquired the necessary educational training for admission into the University of Halle. Here he soon found himself in favor with Professor Bartholemeus Schimpfer,[66] who was counted one of the leading astrologers of the time. In addition to the youthful student’s general duties as secretary to the professor, there was assigned to him the task of calendar making. This was a task which especially appealed to him, and he soon had a following, as a tutor, among those students who like himself found the astrological science one of absorbing interest. Led by the fact that students from the University of Leipzig came to him for instruction, he transferred his residence from Halle to this University, thinking thereby to improve his opportunities for mathematical studies. Here he continued his astrological work, not so much, it appears, because of a genuine belief in the practical value of the science, as such; the rather because he found in its pursuit a good source of income.[67] His theological bent soon led him to a conclusion that the science of astrology rested upon a very unsubstantial foundation. “If God be the creator and supporter of the universe, what an insignificant part,” thought he, “can the stars play in determining the destiny of the individual.”
