Dulinea represents the most disconcerting case in Western literature. She is a character but never appears as a character in the Quijote. However, Dulcinea is a complex character, whose analysis can be started from very different perspectives. Dulcinea is the creation of a creation: she is an invention of Don Qujote de la Mancha, which in turn is an invention of Alonso Quijano, which in turn is an invention of Cervantes. Dulcinea is a necessity so that Alonso Quijano can become Don Quijote. She is one of the elements that the gentleman needs to be knight, because she represents "la Dama" of the chivalrous novel with the courtly love. From there, its characterization serves to the treatment of the loving subject, because she is the spirit that sets in motion the gentleman at the time of undertaking his adventures. But the point of departure of the ideal lady, Dulcinea, is a peasant Aldonza Lorenzo, who works as a parody of courtly love. With this technique, Cervantes considers the Neoplatonism in the Renaissance, which is the aesthetic thought of Christian Neoplatonism. In the theologia Platonica on the immortality of the soul, Cervantes describes the immortality of the love through the character Dulcinea. For Cervanes, Dulcinea symbolizes ‘Beauty’, which is the product of God’s Love as the principle of cosmic harmony and unity. In this way, Dulcinea survives forever after the death of Don Quijote.
