this connection to add an expression of his grateful appreciation for any word which may be sent to him concerning unmentioned examples, to the end that in a revised edition such examples may be fittingly noted. The great war checked the search for existing examples, and prevented the inclusion of many illustrations which had been promised, but these were promises which could not be fulfilled.
An attempt has been made, as before noted, to treat the subject historically, beginning with the earliest references to the belief in a spherical earth and a spherical firmament encircling it. It is not easy to fix, with anything like a satisfactory measure of certainty, the beginning of globe construction; very naturally it was not until a spherical theory concerning the heavens and the earth had been accepted, and for this we are led back quite to Aristotle and beyond, back indeed to the Pythagoreans if not yet farther. We find allusions to celestial globes in the days of Eudoxus and Archimedes, to terrestrial globes in the days of Crates and Hipparchus. We find that the Greek geographer Strabo gives us quite a definite word concerning their value and their construction, and that Ptolemy is so definite in his references to them as to lead to a belief that globes were by no means uncommon instruments in his day, and that they were regarded of much value in the study of geography and astronomy, particularly of the latter science. There is, however, but one example known, which has come down to us from that ancient day, this a celestial globe, which is noted below and briefly described as the Farnese globe. It is of marble, and is thought by some to date from the time of Eudoxus, that is, three hundred years before the Christian era.
To the Mohammedans belongs chief credit for keeping alive an interest in astronomical studies during the so-called Christian middle ages, and we find them interested in globe construction, that is, in celestial globe construction; so far as we have knowledge, it seems doubtful that they undertook the construction of terrestrial globes.
Among the Christian peoples of Europe in this same period there was not wanting an interest in both geography and astronomy. We are now learning that those centuries were not entirely barren of a certain interest in sciences other than theological. In Justinian’s day, or near it, one Leontius Mechanicus busied himself in Constantinople with globe construction, and we have left to us his brief descriptive reference to his work. With stress laid, during the many centuries succeeding, upon matters pertaining to the religious life, there naturally was less concern than there had been in the humanistic days of classical antiquity as to whether the earth is spherical in form or flat like a circular disc, nor was it thought to matter overmuch as to the form of the heavens. Yet there was no century, not even in those ages we happily are learning to call no longer dark, that geography and astronomy were not studied and taught, and globes celestial as well as armillary spheres, if not terrestrial globes, were constructed. The Venerable Bede, Notker Labeo, Pope Sylvester I, the Emperor Frederick II, and King Alfonso of Castile, not to name many others of perhaps lesser significance, displayed an interest in globes and globe making.
The modern age opens with an interest in the expansion of Europe overland eastward, with this interest soon to be followed by greater enthusiasm in transoceanic expansion. With the rapidly increasing knowledge concerning the hitherto unknown or but little known regions of the earth came a desire for better map making, came an interest intelligently directed in the construction of terrestrial globes on which the newly discovered parts might be represented in their relative positions as they are on the real spherical earth. To this interest Martin Behaim gave striking expression, producing in the year 1492 his famous “Erdapfel” referred to above as the oldest extant terrestrial globe. His century closes with every evidence that the spherical theory, as Aristotle had expressed it nearly two thousand years before, could alone be accepted by geographers, and if spherical, the fact could be most impressively taught by the use of a material representation, that is, by means of a terrestrial globe.
The sixteenth century opened with a marvelously increased interest in geography, the result of a climax reached through the transoceanic discoveries in which Columbus led the way. If the makers of plane maps became now increasingly active, so the makers of globes were becoming increasingly numerous, and at first in the countries of trans-alpine Europe. Globes of metal with engraved maps, as the Lenox and the Jagellonicus copper spheres, globes with manuscript maps covering a sphere of special composition, as were those of Schöner, globes in the preparation of which engraved gore maps were employed; as the Waldseemüller, the Boulengier, the Gemma, and the Mercator, make their appearance in ever increasing numbers, the activity encouraged by those interested in a scientific study of geography and astronomy, and notably by seamen, in whose collection of navigator’s instruments they were long considered to be of the greatest importance.
How the globe interest in the several countries of Europe found expression during the sixteenth, seventeenth, and eighteenth centuries is fully set forth in the following pages, with something of an attempt at a grouping and a classification of the results, to the end of making more clear the trend of that interest, now quickened, now retarded, by certain temporary or permanent national impulses.
It is especially interesting to note how a certain superiority in globe making exhibited itself, now in one country, now in another, with a lingering favor exhibited in Italy for the manuscript or the metal globe, while in the North, globes with copper engraved gore maps found increasing favor from the first, with a certain climax reached in the Netherlands in the days of Hondius and Blaeu.
In the appended tabulated list of globes and globe makers, it will be noted that the makers have been listed alphabetically, that the kind of globe has been indicated, whether terrestrial, celestial or armillary sphere, with the date given, though sometimes only approximately, and with the diameter of each globe recorded in centimeters, so far as obtainable with an acceptable degree of accuracy, fractions thereof being omitted, these same measurements being repeated in the text reference to each individual example or edition.
The author had been ambitious to include in his illustrations a reproduction of each known example or edition, showing at least the general appearance of each, but he fully realizes the more or less unsatisfactory character of a small print, and the unsatisfactory results of an attempt to photograph the curved surface of a sphere. Not a few of the many examples would prove to be of the greatest interest and scientific value could the entire map surface have been given in reproduction and in size to be easily legible. It however can be readily understood how such an undertaking was necessarily considered to be unpractical. Out of the author’s collection of about four hundred globe photographs, a selection has been made of those which it has been thought would be most suitable for illustrative purposes.
It is hoped that the preliminary study herewith presented may lead to a number of independent and thorough investigations of important individual examples, to the end of clearly setting forth their great documentary value.
There have been added to the list of illustrations certain important legends as they appear in the original, likewise a number of contemporary portraits of the distinguished globe and map makers of the last three centuries. In most instances important legends have been cited in the text in the exact language of the original, to which, with very few exceptions, a translation is added. The critical student will occasionally be somewhat astounded at the incorrectness of the language, Latin, Italian, Spanish, French or German, in the original. The translations into English, not infrequently, have been made with difficulty; accordingly it will be noted in some instances that the translation is conjectural. No attempt has been made to correct errors; on the contrary, the greatest care has been exercised to adhere faithfully to the original as given by the map or globe maker.
The bibliographical list appended is full, but completeness is not pretended. Practically all of the works cited have been consulted, and care has been taken to include those held to be of the greatest importance. It will at least serve as a working list for those students who may wish to make further investigations within the field under consideration.
An expression of sincerest thanks is here recorded to the very many librarians, directors of museums, and private individuals who have so graciously responded to requests for information concerning the globes belonging to their several collections. The privilege so readily conceded for photographing the several examples, and the time and trouble expended in having this work of reproduction well done, are nothing less than a striking evidence of the kindliest fraternal spirit
