1600 accomodatarum sphaeram accuratissime expolitam et Australibus asterismis quod novum a Federico Houtmano observatis exornatam. Auctor Guilielmo Jansᵒ Blaeu.” “Thou hast here, O lover of the stars, a globe of the fixed stars from the most accurate observations of D. Tycho Brahe (my onetime preceptor) in their number and disposition, besides other observations accommodated to the year 1600, finished and furnished with (a representation) of the southern stars which have of late been discovered by Frederick Houtmann. Willem Jansz. Blaeu author.” Stars varying in magnitude from the first to the sixth, receive each an appropriate representation or sign, and there is a separate distinguishing mark for the nebulae. To each of the constellations is given its Latin name. In addition to the forty-eight constellations of Ptolemy he gives the two sometimes referred to by the ancients, “Bernice’s Hair” and “Antinous,” adding, with names, more than ten constellations in the southern sky. A legend in the constellation “Cepheus” tells us, with reference to one of its stars, “Haec stupendae magnitudinis stella insolito fulgore anno 1572 in Cassiopeia sede amicuit.” “This star of great size and unwonted brilliancy appeared in the Chair of Cassiopeia.” In the constellation “Cygnus” is a legend reading “Novam illam stellam quae anno 1600 primum in pectore Cygni apparuit (atque etiam nunc immota parte) ex diligenti nostra ad eandem Lyrae lucidae observatione Longitudo 16° 15´, latitudo 55° 30´ labore comperimus.” “The new star which in the year 1600 first appeared in the breast of the Swan and to the present has not altogether disappeared, this we have located, by diligent search in Lyra long. 16° 15´ and lat. 55° 30´.” By reason of the fact that so few copies of this issue are known to exist, it has been thought that for some reason Blaeu issued a very limited number. We know, however, that his terrestrial globes were highly valued and were much in demand, because of the care with which they had been prepared, because of the efforts to give information concerning the latest discoveries, and because of his representation of the loxodromic lines which made them of special value to navigators; that his celestial globes found favor by reason of the fact that he was known to be a pupil of Tycho Brahe, and that he himself was known to be a mathematician and astronomer of distinction. To the following known examples of the 1602 issue brief reference may be made. In the Accademia dei Concordi of Rovigo, Italy, there may be found a fine pair. The Stadtbibliothek of Nürnberg possesses a fine pair, reported by the librarian to be in excellent condition, and two copies of the celestial globe may be found in the Germanisches Nationalmuseum of the same city. A copy of the terrestrial globe is to be found in the collection of the Königliches Museum of Cassel, and one in the town of Rüdingen near Schaffhausen.
