Olivia and Orsino are also unintentionally foolish, though less obtuse than Sir Andrew. Both are melancholic, and from this disorder arises folly; Zijderveld includes in his detailing of the spectrum of folly a kind of fool called “melancholicus” (35). It is easy to identify the types of melancholy from which the countess and duke suffer. Olivia’s is clearly derived from her excessive grief over her brother’s death; she tells Valentine that she will mourn for seven years. Orsino’s melancholy finds its origin in his obsessive, unrequited love for Olivia; he enacts the role of the despised courtly lover, surfeiting himself with music, bowers of flowers, and self-pity indeed he seems more in love with love itself than with Olivia.
