There is a third armillary sphere belonging to the Settàla collection, which is of silver and which probably was constructed near the middle of the seventeenth century, although it is neither signed nor dated. It is 40 cm. in height, having a circle representing the ecliptic 15 cm. in diameter, which is graduated, having on its upper surface engraved figures representing the twelve zodiacal constellations. The meridian circle has a diameter of 16 cm., the horizon a diameter of 16 cm. and a breadth of 3 cm., on the upper surface of which have been engraved the names of the months, and the signs of the zodiac. In addition to the parts mentioned it has two small polar circles, and at the common center a small silver ball 1 cm. in diameter representing the earth. Attention has been previously called to the transfer of the business of Jodocus Hondius into the hands of the son-in-law, Johan Janssonius, and of Abraham Goos, by whom it was carried on after the year 1640. This firm continued to issue the Hondius globes, modifying them from issue to issue with the addition of some of the latest geographical information obtainable. In the year 1648, with Johan Janssonius as editor and Abraham Goos as author and engraver, there was issued a pair of these revised Hondius globes, each having a diameter of 87 cm. On the terrestrial globe we read “Amstelodami Edebat Joannes Jansonius Sculpebat magnoque studio componebat Abrahamus Goos Amstelodamensis.” “Amsterdam. Edited by Johan Jansonius. Composed with much study and engraved by Abraham Goos a native of Amsterdam.” Further details concerning this globe have not been obtainable, but it is very certain, although differing in size, it contains practically all the features common to the earlier editions of the Hondius terrestrial globes, and especially of the later ones. The celestial globes have the following inscription: “Sphaera nova summo studio summaque diligentia atque industria Clarissimi viri D. Adriani Metii Watheseos apud Frunequeranos Professoris Ordinarii ad abacos Nobilissimi viri Thiconis Brahe configurata observationibus quamplurimis tum circa polum arcticum a discipulo suo Houtmanno adhibitis aucta et in annum 1620 reducta. Edente Joanne Jansonio 1648.” “A new globe constructed with the greatest industry, zeal and diligence accommodated to the tables of the most noble Tycho Brahe, enlarged by very many observations, those around the Arctic pole being made by myself, and those around the Antarctic by his disciple Houtmann. All, accommodated to the year 1630. Constructed by Johan Jansonius, 1648.” A pair of these globes may be found in the library of the Marquis Borromeo of Milan. NOTES
