Moller says: “Nec silentio sunt involvenda duo admiranda orbis authomata astronomico-cosmographica, juxta delineationem ipsius ingeniosissimam A. 1654 et seqq. ab And. Boschio Mechanico Dedalaeo et in Mathesi versatissimo, dirigente laborem Ad. Oleario, Principis hujus sui etiam mathematici, fabrefacta, quibus similis Europam, imo orbem majorem universum, non vidisse, praeter Olearium Heun. Heuningi et D. G. Morphosius sunt persuasi....” Weidler, J. F. Historia astronomiae. Wittenberg, 1741, p. 541. Weidler says: “Globum a. 1654 Fredericus dux Holsatiae, dirigente opus Adamo Oleario, e cupro fabrefieri et in arce Gortorpiensi curaverat. Diameter ejus 10-1/2 pedes capiebat, totusque globus rotis, flumine circumjactis movebatur.” [64] Günther-Fiorini. Erd- und Himmelsgloben, p. 83; Royal Geographical Journal. London, 1901. p. 219.

Armillary Sphere and Celestial Globe of Ferdinand Verbiest, 1673.] [66] Schimpfer was a native of Nürnberg and active in his profession about the middle of the seventeenth century. [67] Bartholomaei, op. cit. [68] Bartholomaei, referring to the popularity of Weigel as a lecturer, states that some of his lectures were given in the open because there was no available room sufficiently large to accommodate his hearers.

In a very early day the Venerable Bede had suggested a change from the heathen names of the several constellations to Christian names. See in this connection Schiller, J. Coelum stellatum christianum. Augsburg, 1627. Schiller was a pupil of the famous astronomer, Johannes Bayer, from whom he probably received his impulse to inaugurate a reform in the matter of naming the constellations. Schiller felt much annoyed that heathen names for stars and star groups should be retained by Christian peoples, and it was probably with Bayer that he worked out his scheme for a new nomenclature. To the twelve signs of the zodiac, for example, he gave the names of the twelve apostles. For the constellation Perseus he proposed the Apostle Paul, for the Great Bear the Ship of Peter, for Hercules the Three Kings, for Cassiopeia the name Maria Magdalena, for Auriga Saint Jerome; he further proposed to change the name Ophiuchus to Pope Benedict, Pegasus to the Angel Gabriel, Orion to Joseph, Canis Major to King David, the Ship Argo to the Ark of Noe, the Centaur to Abraham, the Peacock to Eve.
