Abstract: Resituated in the theatrical context of the Richelieu years, the three tragedies presented in this volume, La Mariane, La Mort de Sénèque, and Osman, bear witness to a problematic tension between the tyrannical exercise of political power and the affirmation of heroic values imbued with the Stoic ideal.
