Within the Arctic circle and north of North America is the title and
date legend reading “Globus Terrestris de integri revisus & emendatus
an. 1600.” “Globe of the entire earth revised and corrected in the year
1600.” To the right of the dedicatory legend we find instruction given
as to the method of finding the direction from one place to another, of
which one may be desirous of having knowledge; it reads: “Modus
investigandi locorū directionē. Duorum locorum in hoc globo quorum
directionem scire cupis hoc est in quam coeli partem alter ab altero
vergat, primo longitudinis et latitudinis differentiam notabis, qua
cognita vertas globum donec Rhumbus aliquis intersecet meridianum in
latitudinē primi loci, deinde volvas versus Ortum aut Occasum, prout res
postulat, donec gradus aequatoris numero aequales differentiae
longitudinis duorū locorum meridianum pertranseant postea vide num
assūptus Rhumbus intersecet meridianum in latitudine loci. Quod si
fecerit hic est horum locorū Rhumbus sive linea directionem indicans:
sin secus, alius assumendus est, usque dum occurrat qui hoc
praestiterit. Subjecimus scalam longitudinum.” “Of two places on this
globe whose direction from one another you are desirous of knowing, that
is in what part of the heavens the one diverges from the other, first of
all note the difference of latitude and longitude. This ascertained turn
the globe until some one rhumb cuts the meridian in the latitude of the
first place, then turn to the east or to the west as is required, until
the degrees of the equator through which the meridians of the places
pass equal in number the difference in longitude of the two places. Then
note whether the selected rhumb cuts the meridian in the latitude of the
place. If it does so then this is the rhumb of these places or the line
which shows the required direction: but if it does not then another
rhumb must be chosen until the condition is satisfied. We subjoin a
scale of longitudes.” Other legends, describing briefly some event in
the history of discovery, or describing briefly the characteristic
features of some locality, are exceedingly numerous. As a record of the
geographical knowledge of the time, this Hondius terrestrial globe map
may justly be referred to as one of the most valuable of the period.
