THUANUS (Jacobus Augustus), youngest son of the president de Thou, was famous for the depth and erudition of his works. He was born in 1553; and having finished his studies and travels, was made president a-Mortier, and took possession thereof in 1595. He was employed in several important offices of state, and in reforming the uni-
versity of Paris; which he discharged with so much prudence, that he was esteemed the Cato of his age, and the ornament of France. He wrote the history of his own time in Latin, from the year 1543 to 1608, in 138 books; a work, both for subject and style, worthy of the ancients. He also left memoirs of his own life, besides poems; and died at Paris, 1617.
