Among the éloges by Bailly, there is one, that of the Abbé de Lacaille, which not having been written for a literary academy, shows no longer any trace of inflation or declamation, and might, it seems to me, compete with some of the best éloges by Condorcet. Yet, it is curious, that this excellent biography contributed, perhaps as much as D'Alembert's opposition, to make Bailly's claims fail. Vainly did the celebrated astronomer flatter himself in his exordium, "that M. de Fouchy, who, as Secretary of the Academy, had already paid his tribute to Lacaille, would not be displeased at his having followed him in the same career ... that he would not be blamed for repeating the praises due to an illustrious man."
Bailly, in fact, was not blamed aloud; but when the hour for retreat had sounded in M. de Fouchy's ear, without any fuss, without showing himself offended in his self-love, remaining apparently modest, this learned man, in asking for an assistant, selected one who had not undertaken to repeat his éloges; who had not found his biographies insufficient. This preference ought not to be, and was not, uninfluential in the result of the competition.
Bailly, if Perpetual Secretary of the Academy, would have been obliged to reside constantly at Paris. But Bailly, as member of the Astronomical Section, might retire to the country, and thus escape those thieves of time, as Byron called them, who especially abound in the metropolis. Bailly settled at Chaillot. It was at Chaillot that our fellow-academician composed his best works, those that will sail down the stream of time.
Nature had endowed Bailly with the most happy memory. He did not write his discourses till he had completed them in his head. His first copy was always a clean copy. Every morning Bailly started early from his humble residence at Chaillot; he went to the Bois de Boulogne, and there, walking for many hours at a time, his powerful mind elaborated, coördinated, and robed in all the pomps of language, those high conceptions destined to charm successive generations. Biographers inform us that Crébillon composed in a similar way. And this was, according to several critics, the cause of the incorrectness, of the asperity of style, which disfigure several pieces by that tragic poet. The works of Bailly, and especially the discourses that complete the History of Astronomy, invalidate this explanation. I could also appeal to the elegant and pure productions of that poet whom France has just lost and weeps for. No one indeed can be ignorant of his works; Casimir Delavigne, like Bailly, never committed his verses to paper until he had worked them up in his mind to that harmonious perfection which procured for them the unanimous suffrages of all people of taste. Gentlemen, pardon this reminiscence. The heart loves to connect such names as those of Bailly and of Delavigne; those rare and glorious symbols, in whom we find united talent, virtue, and an invariable patriotism.
HISTORY OF ASTRONOMY.—LETTERS ON THE ATLANTIS OF PLATO AND ON THE ANCIENT HISTORY OF ASIA.
In 1775, Bailly published a quarto volume, entitled History of Ancient Astronomy, from its Origin up to the Establishment of the Alexandrian School. An analogous work for the lapse of time, comprised between the Alexandrian School and 1730, appeared in 1779, in two volumes. An additional volume appeared three years later, entitled the History of Modern Astronomy up to the Epoch of 1782. The fifth part of this immense composition, the History of Indian Astronomy, was published in 1787.
When Bailly undertook this general history of Astronomy, the science possessed nothing of the sort. Erudition had seized upon some special questions, some detailed points, but no commanding view had presided over these investigations.
Weidler's book, published in 1741, was a mere simple nomenclature of the astronomers of every age, and of every country; the dates of their birth and death; the titles of their works. The utility of this precise enumeration of dates and titles did not alter the character of the book.
Bailly sketches the plan of his work with a masterly hand in a few lines; he says, "It is interesting to transport one's self back to the times when Astronomy began; to observe how discoveries were connected together, how errors have got mixed up with truth, have delayed the knowledge of it, and retarded its progress; and, after having followed the various epochs and traversed every climate, finally to contemplate the edifice founded on the labours of successive centuries and of various nations."
