After some considerable time spent in making collections for the work which is now submitted to the public, I became aware that a biography of Michael Scot was in existence which had been composed as early as the close of the sixteenth century. This is the work of Bernardino Baldi of Urbino, who was born in 1553. He studied medicine at Padua, but soon turned his attention to mathematics, especially to the historical developments of that science. Taking holy orders, he became Abbot of Guastalla in 1586, and in the quiet of that cloister found time to produce his work ‘De le vite de Matematici’ of which the biography of Scot forms a part. He died in 1617. This discovery led me at first to think that my original plan might with some advantage be modified. Baldi had evidently enjoyed great advantages in writing his life of Scot. His time lay nearer to that of Scot by three hundred years than our own does. He was a native of Italy, where so large a part of Scot’s life was passed. He had studied at Padua, the last of the great schools in which AverroËs, whom Scot first introduced to the Latins, still held intellectual sway. A serious difficulty, however, here presented itself, and in the end proved insuperable, as I was quite unable to gain access to the work of Baldi. It seems to exist in no more than two manuscripts, both of them belonging to a private library in Rome, that of the late Prince Baldassare Boncompagni, who had acquired them from the Albani collection. The Boncompagni library has been now for some time under strict seal, pending certain legal proceedings, and all my endeavours to get even a sight of the manuscripts were in vain. In these circumstances I fell back upon a printed volume, the Cronica de Matematici overo Epitome dell’Istoria delle vite loro, which is an abbreviated My study of the life and times of Scot thus resumed its natural tendency towards an independent form, there being no text known to me that could in any way supply the want of an original biography. It is for the reader to judge how far the boldness of such an attempt has been justified by its success. The difficulties of the task have certainly been increased by the want of any previous collections that could be called satisfactory. Boece, Dempster, and NaudÉ yield little in the way of precise and instructive detail; their accounts of Scot fall to be classed with that of Baldi as partly incorrect and partly commonplace. Schmuzer alone seems by the title of his work This failure in the department of biography already formed has obliged me to a more exact and extensive study of original manuscript sources for the life of Scot than I might otherwise have thought necessary, and has proved thus perhaps rather of advantage. It is inevitable indeed that a work of this kind, undertaken several ages too late, should be comparatively barren in those dates and intimate details which are so satisfactory to our curiosity when we can fall upon them. In the absence of these, however, our attention is naturally fixed, and not, as it seems to me, unprofitably, on what In the course of researches among the libraries of Scotland and Italy, of England and France, of Spain and Germany, I have received much kindness from the learned men who direct these institutions. I therefore gladly avail myself of this opportunity to express my thanks in general to all those who have so kindly come to my help, and in particular to Signor Comm. G. Biagi, and Signor Prof. E. Rostagno of the Laurentian Library; to Signore L. Licini of the Riccardian Library; to the Rev. Padre Ehrle of the Vatican Library; to Signor Cav. Giorgi, and the Conte Passerini of the Casanatense; to Signor Prof. Menghini of the Vittorio Emanuele Library, Rome; and to Signor Comm. Cugnoni of the Chigi Library. I am also much If the result of my studies should prove somewhat disappointing to the reader, I can but plead the excuse with which Pliny furnishes me, it is one having peculiar application to such a task as is here attempted: ‘Res ardua,’ he says, ‘vetustis novitatem dare, novis auctoritatem, obsoletis nitorem, obscuris lucem, fastiditis gratiam, dubiis fidem, omnibus vero naturam, et naturae suae omnia.’ 17 Via Montebello, |
