Eminent French scholar, learned in Greek, Latin, Hebrew, Arabic, and other languages; succeeded Scaliger at Leyden, and associated with Casaubon, Grotius, and other scholars; embraced Protestantism; wrote a number of learned works, but his "Defence of Charles I." proved a failure, and provoked from Milton a crushing reply; died a disappointed man, though he refused to sell his literary talent for money, when Richelieu tried hard to bribe him (1588-1653).
