How did Filodemo build on the Portuguese auto tradition?

In his play Filodemo, Luís de Camões built upon the Portuguese auto tradition—a dramatic genre popularized by Gil Vicente—by introducing several structural and stylistic refinements.1

Camões modernized the morality play format through the following innovations:

• Classical Restraint: He imposed a sense of classical discipline on the traditional Vicentian auto.1
• Plot Development: He increased the overall importance and complexity of the plot.1
• Shift in Comedy: He moved the comic element away from the characters themselves and integrated it into the action of the play.1
• Refinement: He refined the farce elements inherent in the genre.1

Although these changes indicated a potential path for rejuvenating 16th-century Portuguese comedy, Camões viewed his dramatic works as mere recreations, and subsequent dramatists were unable to build upon the lead he provided.1
