GROLIER, JEAN, VICOMTE D'AIGUISY (1479-1565), French bibliophile, was born at Lyons, was the friend of Bude, the patron of Aldus, and was called the Maccenas of men of letters by his contemporaries. Of his great library of 3,00o volumes, dispersed in 1675, some 3 5o are known to be in existence. They are richly bound and bear their owner's ex libris "Grolerii Lugdunensis, et Amicorum." Grolier made the acquaintance of Aldus while he was French ambassador in Italy (I 510-3 5) • See Leroux de Lincy, Recherches sur Jean Grolier (1866) .
