He was certainly the leading bibliophile of his day, at once the most cultivated and the most liberal in the acquisition of rare books. Contemporary writers mention his literary taste and his fine library, which at the time of his death contained about 40,000 volumes. These he left to a member of his family, Robert Bigot (who also had a book-plate), but eventually they were sold in Paris in 1706. The following ex-libris have also been identified as belonging to this period, either by the names, the arms, the mottoes, or by the signatures of the artists affixed to them: Charles de Lorraine, Evêque de Verdun (1592-1631). Fine armorial plate, without the owner’s name. Alexandre Bouchart, Sieur de Blosseville. Engraved by Léonard Gaultier, dated 1611, and already described on page 12. Melchior de la Vallée, dated 1613, an armorial plate of extreme rarity. The inscription reads thus: “Melchior a Valle protonotarius Insignis Ecclæ Sancti Georgi Naceis Cantor et Canonicus Henr II. D. Lotharin. et Barri eleemosinarius.” On account of its extreme rarity this ex-libris had long been the subject of doubt and curiosity to collectors, even Mons. Poulet-Malassis had not seen it, and blundered in his notes upon it. At length Dr. Bouland gave a _facsimile_ of it in the _Archives de la Société Française_ for February, 1895. The actual engraving measures exactly six inches by four, and in the lower portion the date (1613) is boldly engraved. Dr. Bouland, in his notes upon it, says that this _facsimile_ is taken from the only original copy that is now known to exist, in the possession of Mons. Lucien Wiener, Curator of the Lorraine Museum in Nancy. One other example was discovered some time since, but was unfortunately destroyed in a fire. The design (which it may be said is more curious than beautiful) was at first attributed to Callot, but it is now believed to have been the work of Jacques Bellange, a painter and engraver, who was born in Nancy in 1594, and died about 1638, consequently he might well have produced work of this description in 1613. Melchior de la Vallée was an ecclesiastic, with a passion for collecting rare books and curiosities; unfortunately he incurred the displeasure of Charles IV., Duke of Lorraine, was accused of sorcery, and cruelly burnt alive in 1631. Chanlecy. The nameless armorial plate of an ecclesiastic belonging to this Burgundian family, quartering the arms of Semur and Thiard. Claude Sarrau. Armorial plate in two sizes; the larger one only is signed Briot, although it is probable the same artist, Isaac Briot, engraved both. The owner’s name does not appear on either plate. Claude Sarrau, councillor to the parliament of Paris, died in 1651. His correspondence with the savants of the day was edited and published by his son Isaac in 1654.
