As early as 1503 however, original language versions of Sophocles, Seneca, Euripides, Aristophanes, Terence and Plautus were all available in Europe and the next forty years would see humanists and poets both translating these classics and adapting them. In the 1540s, the French university setting (and especially — from 1553 on — the Jesuit colleges) became host to a Neo-Latin theater (in Latin) written by professors such as George Buchanan and Marc Antoine Muret which would leave a profound mark on the members of La Pléiade. From 1550 on, one finds humanist theater written in French.
