The article deals with intertextual relationships of the xviiith century tragedy : these relationships are particularly rich, because the contemporary dramatist partly seeks a theme in the works of ancient authors, and he partly uses contemporary drama procedures and he separates himself from dramas/plays with the same subject. The characteristic feature of processing of the play of the same idea is transmotivation and revaluation, which functioning is supported by author’s analysis of Voltaire’s tragedy “Rome sauvée ou Catilina”, taking into account Voltaire’s rivals plays — Catiline by Ben-Johnson and especially Catilina by Crébillon. Just the confrontation of these plays allows defining principles of Voltaire’s dramaturgy : the structural role of love in motivating acts and the moral elevation of the hero, who has to be an example.
