Table of Contents

HITHERTO there has not appeared in English a detailed historical treatise on globes terrestrial and celestial. The publications are somewhat numerous, it is true, in which a very general consideration has been given to the uses of globes, including a reference to their important structural features, and to the problems geographical and astronomical in the solution of which they may be counted of service. There are a few studies, critical and historical, touching certain selected examples of the early globe maker’s handiwork which can be cited. Attention, for example, may here be directed to Sir Clements Markham’s valuable introduction to his excellent English translation of Hues’ ‘Tractatus de Globis,’ a work originally prepared for the purpose of furnishing a description of the Molyneaux globes, in which introduction he undertook “to pass in review the celestial and terrestrial globes which preceded or were contemporaneous with the first that were made in England (1592) so far as a knowledge of them has come down to us,” yet the learned author cites but a fraction of the many globes referred to in the following pages. In Ravenstein’s ‘Behaim, His Life and His Globe,’ we have perhaps the most scholarly treatment of its kind in any language, but the study is limited to the work of one man, the maker of the oldest extant terrestrial globe, which is dated 1492.

The bibliographical list which is appended gives striking evidence that there has been a more or less extended interest in the general subject of the use and the construction of globes in France, in Germany, in England, and in Italy. The author makes in this place special mention of his indebtedness to the studies of the distinguished Italian scholar, Professor Matteo Fiorini, adding that with some propriety his name might have a place on the title-page. Had there not been a ready access to his important works, had the Italian Geographical Society not so graciously expressed to the author its willingness for the free use of as much of his published investigations as might be desired, for which it stood in the relation of sponsor publisher, a willingness which Fiorini himself had assured to any who might have access to the printed results of his studies within this field, the preparation of this work necessarily would have extended over a considerable period of time. Special mention must be made of his ‘Sfere Terrestri e Celesti di Autore Italiano oppure fatte o conservate in Italia,’ and of his ‘Sfere cosmografiche e specialmente le Sfere Terrestri.’ These works have been of very signal value for the study of the Italian globes and globe makers. Not an inconsiderable part of his descriptive details has been appropriated, being given in free translation or in paraphrase, quotation marks having been omitted. Special mention may also here be made of Sigmund Günther’s interesting little volume, which he titles ‘Erd- und Himmelsgloben nach dem italienischen Matteo Fiorinis frei bearbeitet.’ This has been of special value for its bibliographical references and for its short chapters on globe-gore construction.

To attempt the listing, with description, of all globes known to have been constructed from the earliest times to the close of the eighteenth century, the latter being a somewhat arbitrary date, is pretentious. The fact is fully appreciated that in many instances the description given is all too brief. Many of the individual terrestrial globe maps of the period in question, it should be especially noted, are of the greatest historical and scientific value; but to have undertaken a more detailed and a more critical study merely of those which may be called the most important might well have demanded far more time and special research than could have been fittingly allowed for a general survey such as has here been planned; in such a course we should indeed have been led afield from our purpose.

It had been thought when this study was first undertaken that perhaps as many as one hundred existing examples might be located, and that in addition to these not a few important references might be found to work actually done but now lost. Instead of the one hundred, more than eight hundred and fifty have been listed, and from the interesting experience in collecting material for the work, the pleasurable hope is entertained that the published record of this effort will be in some measure the means of bringing to light not a score but scores of other examples. Indulging this hope there have been added to each copy of the book a few blank pages for the insertion of a reference to any not mentioned in the following printed pages. The author begs in 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 existing among those engaged in scientific and literary pursuits the world over. To the requests presented even the antipodes have responded.

In concluding, the author might refer to his interest in globes as dating from his early boyhood days, when, in that country school in western Illinois, bearing the name Liberty, for it had been established in the first years of the Civil War, he studied his geography and indeed his astronomy lessons with the aid of a terrestrial globe and an orrery. Can it be that we have revised our educational methods so far in this country as practically to have eliminated the intelligent use of aids so valuable in the study of the branches which globes concern? They enter in fact but little into modern methods of instruction. If this work could be made to encourage their extensive use, and serve in their rehabilitation as aids of inestimable interest and value in geographical and astronomical studies, it will have served the purpose which is most pleasing to the author.
