Celestial and terrestrial globes by Blaeu
This pair of globes is by the celebrated Dutch cartographer and instrument-maker Wilhelm Janszoon Blaeu (1571Z1638). The terrestrial globe [2] is dated 1599 and the celestial [1] 1603, but the information on the terrestrial globe indicates that it is a later edition, after 1618. The terrestrial globe is dedicated to the Governors of the Estates-General of the Netherlands and the celestial to the Prince of Orange. The celestial globe is derived from the observations of Tycho Brahe, supplemented by the those of Frederik de Houtman made in the southern hemisphere during the first Dutch voyage to the East Indies. Blaeu had worked under Tycho at Uraniborg and has included a portrait of the Danish astronomer on the celestial globe.
