Grolier's books were generally stamped with the words 'et Amicorum' immediately after his name, to indicate as we suppose that they were the common property of himself and his friends, although it has been suggested that he was referring to his possession of duplicates. Another of his marks was the use of some pious phrase, such as a wish that his portion might be in 'the land of the living,' which was either printed on the cover or written on a fly-leaf, if the volume were the gift of a friend. In the use of these distinctions he seems to have been preceded by Thomas Maioli, a book-collector of a family residing at Asti, of whom very little is known apart from his ownership of books in magnificent bindings. Grolier may have borrowed the phrase about his friends from a celebrated Flemish collector called Marcus Laurinus, or Mark Lauwrin of Watervliet, who was in constant correspondence with the Treasurer about their cabinets of medals and coins. Rabelais had a few valuable books, which he stamped with a similar design in Greek, and the Latin form occurs in many other libraries. We are inclined to refer the origin of the practice to a letter written by Philelpho in 1427, in which he tells his correspondent of the Greek proverb that all things are common among friends.
Grolier's love of learning is shown by his own letters, and by the statements contained in the books that were so constantly dedicated to his name. To Beatus Rhenanus he wrote, with reference to an approaching visit: 'Oh, what a festal day, to be marked (as they say) with a pure white stone, when I am able to pay my humble duty to my own Rhenanus; and you see how great are my demands when you are entered as mine in my accounts.' As controller of the Milanese district he became the object of much adulation, for which his flatterers had to atone when the French occupation came to an end. The dedication of a certain dialogue affords an instance in point. Stefano Negri sent his book to Grolier in a splendid shape. The presentation copy on vellum may be seen at the British Museum among the treasures of the Grenville Library. The writer represents himself in the preface as going about in search of a patron. He sees Mercury descending from the clouds with a message from Minerva. 'There is one man whom the Goddess holds dear, struggling like Ulysses through the flood of this stormy life: he is known as Grolier to the world.' Nay, what need have you, says the author, to sing the praises of that famous man? 'You must confess, even if you like it not, that he is most noble in his country and family, most wealthy in fortune, and most fair and beautiful in his bodily gifts.'
As patron of all the arts the treasurer became the friend of Francino Gafori, the leader of the new school of music that was flourishing at Milan. Gafori seems to have been often in Grolier's company. He dedicated to the treasurer his work on the harmony of musical instruments, as well as the Apologia in which he afterwards convicted the Bologna school of its errors. 'My work,' he says in his later book, 'is sound enough if soundly understood'; and he tells his rival that, though he may writhe with rage, the harmony of Gafori and the fame of Jean Grolier will live for ever. The introduction to his work upon harmony contains a few interesting details about Grolier's way of living at Milan. Gafori addresses his book in a dialogue, and vows that it shall never come home again if Grolier refuses to be the patron. A poetical friend adds a piece in which the Muses appear without their proper emblems, and even Apollo is bereft of his lyre. Gafori, they say, has taken away their harmonies and will not give them back. They are advised to make their way to the concert at Grolier's house, where the friend of the Muses sits among the learned doctors. An illustration shows Gafori sitting at his organ and the musicians with their wind-instruments at the end of the lofty hall. Gafori himself, in another preface, declares that his musical offspring can hardly be kept at home; they used to be too shy to go out, though all the musicians were awaiting them; now that they have Grolier's patronage they are all as bold as brass, and ready to rush through any danger to salute their generous friend. The history of the copy presented to Grolier is not without interest. After the great musician's death the treasurer gave it to Albisse, one of the King's secretaries: Albisse in 1546 gave it to Rasse de Neux, a surgeon at Paris, who was devoted to curious books; in 1674 it entered the library of St. Germain-des-Prés, and was nearly destroyed more than a century afterwards in a great fire. During the Revolution it was added to the collection at the Convent des Célestins, and was afterwards deposited in the Bibliothèque de l'Arsenal, where we suppose that it still remains.
Grolier was fond of giving books to his friends. A commentary on the Psalms with his name and device, now in the National Library at Paris, bears an inscription showing that he had given it to a monk named Jacques Guyard. He presented a fine copy of Marcus Aurelius to his friend Eurialo Silvestri; and there are volumes bearing his name in conjunction with those of Maioli and Laurinus which indicate similar gifts. He is known to have presented several volumes to the President de Thou as a mark of gratitude for assistance during his later troubles. It is somewhat singular that Jacques-Auguste de Thou never succeeded in getting possession of these books, though they had always been kept in his father's library; and they were not, indeed, replaced in the 'Bibliotheca Thuana' until it had become the property of the Cardinal de Rohan. It is interesting to learn that a volume of Cicero was given by Grolier to the artistic printer, Geoffroy Tory of Bourges, who designed the lettering of his mottoes: they were of an antique or 'Roman' shape, and were in two sizes, and proportioned, as we are told, 'in the same ratio to each other as the body and face of a man.' Geoffroy Tory mentioned them in a letter of the year 1523. 'It was on the morrow of the Epiphany,' says the light-hearted artist, 'that after my slumbers were over, and in consciousness of a joyous repast, I lay day-dreaming in bed, and twisting the wheels of my memory round: I thought of a thousand little fancies both grave and gay, and then there came before my mind those antique letters that I used to make for my lord, Master Jean Grolier, the King's councillor, and a friend of the Belles Lettres and of all men of learning, by whom he is loved and esteemed on both sides of the Alps.'
Another testimony comes from Dr. Sambucus, who knew Grolier well when he was living in Paris, and used to be fond of inspecting his cabinet of coins. In the last year of Grolier's life he received a book on the subject with a dedication to himself by the worthy Doctor. Grolier was reminded in the preface of their long talks on antiquarian subjects, and of the kindness which Sambucus had received from the treasurer and the treasurer's father at Milan. 'During the last three years,' says Sambucus, 'I have been enriching my library, and I have added some very scarce coins to the cabinet that you used to admire.' He adds a few complaints about dealers and the tricks of the trade, which we need not repeat. 'And now farewell!' he ends, 'noble ornament of a noble race, by whose mouth nothing has ever been uttered that came not from the heart!'
Some account of Grolier's career is to be found in De Thou's great history. He praised the 'incredible love of learning' that had earned for a mere youth the intimate friendship of Budæus. He showed with what administrative ability the Milanese territories were governed, and with what dignity Grolier filled the high office of Treasurer at home.
Grolier, he says, built a magnificent mansion in the Rue de Bussy, which was known as the Hôtel de Lyon; in one of its halls he arranged the multitude of books 'so carefully, and with such a fine effect, that the library might have been compared to that which Pollio established in Rome'; and so great was the supply that, notwithstanding his many gifts to friends and various misfortunes which befell his collection, every important library in France was able after his death to show some of his grand bindings as its principal ornament. Grolier's old age was disturbed by imputations against his official conduct, and it seemed at one time as if his fortune were in considerable danger. 'He was so confident in his innocence,' said the historian,'that he would not seek help from his friends; but he might have fallen at last, if he had not been protected by my father the President, who always used his influence to help the weak against the strong and the scholar against the ignorance of the vulgar.' The old Treasurer kept his serene course of life until he reached his eighty-sixth year: he died at his Hôtel de Lyon, surrounded by his books, and was buried near the high altar in the Church of St. Germain-des-Prés.
Upon Grolier's death his property was divided among his daughters' families. Some of the books were certainly sold; but the greater part of the library became the property of Méric de Vic, the old Treasurer's son-in-law. Méric was keeper of the seals to Louis xiii. His son Dominique became Archbishop of Auch. They were both fond of books, and took great care of Grolier's three thousand exquisite volumes, of which they were successively the owners. They lived in a large house in the Rue St. Martin, which had been built by Budæus, and here the books were kept until the great dispersion in the year 1676. 'They looked,' said Bonaventure d'Argonne, 'as if the Muses had taken the outsides into their charge, as well as the contents, they were adorned with such art and esprit, and looked so gay, with a delicate gilding quite unknown to the book-binders of our time.' The same visitor described the sale of 1676. All Paris was to be seen at the Hôtel de Vic. 'Such a glorious collection ought all to have been kept together; but, as it was, everybody got some share of the spoil.' He bought some of the best specimens himself; and as he was only a poor monk of the Chartreuse the prices can hardly have run high. M. Le Roux de Lincy has traced the fate of the volumes dispersed at the sale. We hear, he says, of examples belonging to De Mesmes and Bigot, to Colbert and Lamoignon, Captain du Fay, the Count d'Hoym, and the Prince de Soubise. Some of the finest were purchased by Baron Hohendorf and were transferred about the year 1720 to the Imperial Library at Vienna. Yet they never rose to any high price until the Soubise sale towards the end of the last century, when the weight of the English competition for books began to be felt upon the Continent.
M. de Lincy has traced the adventures of more than three hundred volumes, once in Grolier's ownership, but now for the most part in public libraries. The earlier possessors are classified according to the dates of their purchases. Of those who obtained specimens soon after the old Treasurer's death we may notice especially Paul Pétau the antiquarian, De Thou the historian, and Pithou the statesman and jurist. Perhaps we should add Jean Ballesdens, a collector of fine books and mss., whose library at his death in 1677 contained nine of Grolier's books, and Pierre Séguier, to whom Ballesdens acted as secretary; and as Séguier was the personal friend of Grolier, he may have been the original recipient of some of the volumes in question.
Pierre Séguier founded a library which became one of the sights of Paris. His grandson, Charles Séguier, the faithful follower of Richelieu, was celebrated for his devotion to books. He used to laugh at his own bibliomania. 'If you want to corrupt me' he would say, 'you can always do it by giving me a book.' His house in the Rue Bouloi served as headquarters for the French Academy before it gained a footing in the Louvre; and on Queen Christina's visit in 1646 one of her first literary excitements was to visit Chancellor Séguier's salon. The decorations were considered worthy of being engraved and published by Dorigny. The gallery stood between two large gardens. The ceilings were encrusted with mosaics on a gold ground with allegorical designs by Vouet. The upper story contained about 12,000 books, and as many more were ranged in the adjoining rooms, one large hall being devoted to diplomatic papers, Greek books from Mount Athos, and Oriental mss. According to a description published in 1684 a large collection of porcelain was arranged on the walls above the book-cases and in cases set cross-wise on the floor: 'the china covered the whole cornice, with the prettiest effect in the world.' We are reminded of the lady's book-room which Addison described as something between a grotto and a library. Her books were arranged in a beautiful order; the quartos were fenced off by a pile of bottles that rose in a delightful pyramid; the octavos were bounded by tea-dishes of all shapes and sizes; 'and at the end of the folios were great jars of china placed one above the other in a very noble piece of architecture.'
