The other famous library was amassed by 'an extraordinary family of book-collectors.' It was begun by Guillaume de la Moignon, who was President of the Parliament of Paris in 1658. His son Chretien de la Moignon was as zealous a book-buyer as his father, and he secured the renown of their library by engaging the services of Adrien Baillet. Dibdin quoted passages from Baillet's biography that show the tenderness with which the family treated his 'crazy body and nervous mind': 'Madame La Moignon and her son always took a pleasure in anticipating his wishes, soothing his irritabilities, promoting his views, and speaking loudly and constantly of the virtues of his head and heart.' Baillet in his turn gave to his employers the credit of his best literary work. 'It was done for you,' he wrote, 'and in your house, and by one who is ever yours to command.' The library was much enlarged by its owner in the third generation; and by its union with the collection of M. Berryer, who died in 1762, it became 'one of the most splendid in Europe.' It was dispersed during the troubles of the Revolution, and a great portion was brought to London in 1791; but the works on jurisprudence were reserved, and were sold in Paris a few years afterwards. David Ancillon is perhaps best known as the defender of Luther and Calvin. But according to Bayle he was an indefatigable book-collector, and notable for having set the fashion of buying books in the first edition. Most people thought, said D'Israeli, that the first edition was only an imperfect essay, 'which the author proposes to finish after trying the sentiments of the literary world.' Bayle was on the side of Ancillon. There are cases, as he remarked, in which the second edition has never appeared; and at any rate the man who waits for the reprint shows 'that he loves a pistole better than knowledge.' Ancillon, however, always indulged himself with 'the most elegant edition,' whatever the first might have been; he considered that 'the less the eyes are fatigued in reading or work the more liberty the mind feels in judging of it.' It is easier to detect the merits in print than in manuscript: 'and so we see them more plainly in good paper and clear type than when the impression and paper are bad?' Some have thought it better to have many editions of a good book: 'among other things,' says our critic, 'we feel great satisfaction in tracing the variations.' Ancillon was naturally accused of an indiscriminate mania for collecting; and he confessed that he was to some extent infected with the 'book-disease.' It was said that he never left his books day or night, except when he went to preach to his humble congregation. He was convinced that some golden thought might be found in the dullest work. Ancillon remained in France as long as his religion was tolerated. He found a home across the Rhine after the revocation of the Edict of Nantes; but from that time he had to
