The Hispanic Society of America possesses a fine example of Blaeu’s early globe work. It is small in size, having a diameter of 13 cm., and is well preserved. Near the upper part of North America is the legend inscribed in a neat cartouche, “NOVA et accurata Terra marisque Sphera, denuo recognita et, correcta á Guilielmo Blaeu,” and in a second legend placed to the south of “Nova Guinea,” which is represented as a part of the great south polar continent of “Magallanica,” he inscribes his name with date, “Guilielmus Blaeu Anno D. 1606.” There may likewise be found in this Society’s rich collections a terrestrial and a celestial globe by Blaeu which clearly are companion pieces and which appear to be unique, the latter dated 1616, the former undated.[36] These globes have a diameter of but 10 cm., a substantial and artistic mounting of brass, including meridian circle, horizon circle, four twisted support columns and a circular base plate. In geographical and astronomical details they are remarkably full, a fact especially noteworthy when their size is taken into consideration. The first he designates as “NOVA ORBIS TERRARVM DESCRIPTIO” and adds to this merely the name “Blaeu”; the second he calls a “Sphaera stellata,” and in a legend he honors his teacher Tycho Brahe by making special mention of his name, signing himself “Guilielmus Blaeu Auctor excudit 1616.” Fiorini refers to a Blaeu celestial globe in the Barberini Palace at Rome dated 1616, but his description of the same shows conclusively that it is very different from the one referred to above, and he appears to consider its map a print of later date, though perhaps in its main features it was originally engraved in the year designated. The next dated and signed globes of Blaeu appear to be of the year 1622, numerous copies of which the author has been able to locate, but in which, however, slight variations appear. From this time until his death in the year 1638, our globe maker seems to have applied himself most diligently to this work, the globes of his later years being much larger than were those of his early years. This Society possesses a well preserved example of his 1622 terrestrial globe which has a diameter of 69 cm. Its map gives us excellent proof of Blaeu’s superior merit in this field. Its geographical details are most numerous, making it an object of great scientific value. Among the records of special interest, omitting for obvious reasons at this time any extended reference to the work, is the representation of Manhattan as an island, apparently the earliest on a dated map.
