Terrestrial and Celestial Globes Volume 2: Their History and Construction Including a Consideration of their Value as Aids in the Study of Geography and Astronomy
Stevenson, Edward Luther
Geography -- History; Globes
This first issue has a diameter of 34 cm., which is less than that of
Mercator’s globe of the year 1541, but greater than that of the Van
Langren globe of the year 1585.[29] The gores, twelve in number, were
cut seven degrees from the poles, the polar space being covered with a
circular disc. Blaeu, as many other globe makers of his period, found
that by thus dividing the engraved globe map a more nearly perfect
covering for the sphere could be obtained. Meridians and parallels are
drawn at intervals of ten degrees, the prime meridian passing through
the island of Santa Maria in the Azores group. In a conspicuously placed
cartouch he presents his address to the reader. “Spectatori meo S. Hanc
terrae marisque faciem qui aspicis sic inspice ne dispicias: multa hic
mutata, (sed nihil temere) quae, nisi attendas, facile fugiant. Ratio
constructionis in multis nova, sed proba. Gibbum plano, planum globo
commutavimus: duplicato labori: sed certiori: idque ut ventorum spirae
justis per orbem trrarum gyris discurrerent: hinc factum ut in omnibus
terrae oris praeter parallelorum et meridianorum etiam plagae ratio
nobis fuerit habenda. Quae quidem omnia attento spectatori facile
apparebunt. Vale et fruere. Guilielmus Jansonius Alcmariensis auctor et
sculptor. 1599.” “Greeting to my observer. This representation of the
earth and sea, which thou beholdest, be pleased to take note of in this
manner. Many things here have been changed, but nothing without reason,
and unless thou art attentive these things might easily escape thee. The
method of construction is in many points new, but correct. We have
changed that which is relief into the flat, and the flat into the
globular, a double labor but more nearly correct, and we did this that
the directions of the winds throughout the world might be given their
proper (loxodromic) spirals: and we have made a representation of the
coast lines of all shores of the earth, besides a representation of the
parallels and meridians. All this will be seen by the attentive
observer. Farewell, and may you be happy. William Jansz. Alcmar, author
and sculptor. 1599.” Fiorini is of the opinion the expression “multa hic
mutata” in the above quoted inscription indicates that the copies in
which it is found are reprints of an earlier edition, and that it has
been inserted for the purpose of keeping the globe on sale.[30] Is not
the reference rather to this simple fact that Blaeu borrowed much of his
geographical information from others, as he admits, including Mercator
and Van Langren, and that he had merely altered the same to the end of
bringing his records to date? The dedication reads “Noblissimis,
Amplissimis, Clarissimis, D. D. Dominis Ordinibus Foederatarum
Inferioris Germaniae Provinciarum dignissimis fidis Patriae Patribus
hoc terrae marisque Theatrum L. M. Q. Dat, Dicat, Dedicat Cliens Vester
subjectis. Guilielmus Jansonius Alcmarianus.” “To the Most Noble, Most
