It has been recently discovered that the earth globe was realized by using the plaster then covered with papier-mache. Thanks to the inscription placed on the Southern Hemisphere, coincided with the Pacific Ocean it is possible knowing it was printed and realized in Amsterdam by the famous globes' cartographer and manufacturer Willem Janszoon Blaeu. The work is full of decorations and the sign is precise; there are the shapes of continents with figures, animals and indigenous groups. In the ocean, they are painted ships, fishs and it is also present the allegorical representation of Neptune on the throne. Despite of the fact that the date written on the globe is 1640, the year of the work's publication which was successive to the Blaeu's death, the work must be realized before 1630 because California is represented as an island and it was only after that date it was discovered California is a peninsula. In addition to this, the four columns wooden support is typical of the Dutch globe's production of the seventeenth century; on the basis of the support, realized by using polychrome and golden wood, there are the four coats of arms of the Cybo Malaspina family and the below pedestals on four leonine paws.The success of the globes was due to curious people and amateurs passionated of nature and geographical discoveries who loved collect them. In the same room, it is also present the celestial globe with which this is paired. There is a very similar version of both globes stocked at the Galileo Museum of Florence.
