Benavente's portrayal of his hero's split personality is the best feature of his composition, while Lope da Vega's monologues are well executed. In Benavente's work, action begins immediately and the reader learns about the protagonist in the narrative.

Lope de Vega tells all about his hero in Act 1 the action and the similarities to Benavente do not begin until Act 2.

The techniques employed constitute the major difference between the two works. Readers soon learn that the protagonists also had similar backgrounds. The family backgrounds and origins of family fortunes have parallel details. Both heroes fall in love with wealthy maidens of the nobility with whom they eventually elope.

Both men arrive penniless in Naples at a bleak period of their lives anxious to improve their fortunes. Similarities in the fate of the two protagonists are striking. A case in point is a comparison of the two Spanish plays "El Caballero de Illescas" by Lope de Vega (1602) and "Los Intereses Creados" by Jacinto Benavente (1907).
