chunk: Rosaura hides a mythological mystery already utilized by Ariosto. When she goes to Court, she takes on the name of Astraea, the goddess of chastity and justice. Astraea was the last of the immortals to leave earth with the decline of the ages. Her return signals the return of a Golden Age. Many writers of the Renaissance and early modern periods used the figure of Astraea to praise the rulers of their times. It is possible that Rosaura (an anagram of auroras, "dawns") could represent the return of a Golden Age during the reign of Segismundo, a figure that represents King Philip IV of Spain.
