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.
