In the early seventeenth century nine lovers of literature associated themselves for the purpose of holding a friendly symposium, where they discoursed of books, and read and criticised each other's compositions; the meetings were followed by a modest repast and a peripatetic discussion. The masterful cardinal, who would rule the French language as well as the state, called the nine together, and in 1635 organised them into an Académie Française, whose function should be to perfect and watch over the purity of the French tongue. The Parlement granted letters-patent, limited the number of academicians to forty, and required them to take cognisance of French authors and the French language alone. The original nine, however, were far from gratified, and always regretted the "golden age" of early days. Richelieu established the Jardin des Plantes for the use of medical students, where demonstrations in botany were given; he rebuilt the college and church of the Sorbonne where his monument,[129] a masterpiece of sculpture by Girardon from Lebrun's designs, may still be seen. He cheapened the postal service,[130] established the Royal Press at the Louvre which in twenty years published seventy Greek, Latin, Italian and French classics. He issued the first political weekly gazette in France, was a liberal patron of men of letters and of artists, and saw the birth and fostered the growth of the great period of French literary and artistic supremacy. Another of Henry the Fourth's plans for the aggrandisement of Paris was carried out by the indefatigable minister. As early as 867 the bishops of Paris had been confirmed by royal charter in their possession of the two islands east of the Cité, the Isle Notre Dame and Isle aux Vaches. From time immemorial these had been used as timber-yards, and in 1616 the chapter of the cathedral was induced to treat with Christophe Marie, contractor for the bridges of France and others, who agreed to fill in the channel,[131] which separated the islands; to cover them with broad streets of houses and quays, and to build certain bridges; but expressly contracted never to fill up the arm of the Seine between the Isle Notre Dame, and the Cité. The first stone of the new bridge which was to connect the islands with the north bank was laid by Louis XIII. in 1614 and named Pont Marie, after the contractor. In 1664 a church, dedicated to St. Louis, was begun on the site of an earlier chapel by Levau, but not completed until 1726 by Donat.
