Despite its ludic appearance, “The adventure Don Quixote had with a dead body” (part I, chapter XIX) is one of the most complex pieces of Cervantes’ famous novel. In the midst of a dark night, the Manchegan knight errant confronts an otherwordly procession of robed men carrying torches who transport a dead “knight” on a bier. Don Quixote attacks them to “avenge” the mysterious dead man, discovering they were priests secretly taking the body from Baeza to Segovia. He wants to see face to face the relic of the dead body, but humbly turns his back, avoiding the “close encounter”. Curiously enough, his easy victory renders him sad. Cervantes is alluding to the secret transfer of St. John of the Cross’ body from Úbeda to Segovia, claimed by the devoted widow Doña Ana de Peñalosa. However, Cervantes is also establishing a surprising dialogue with St. John’s symbolic “dark night”, in which he fights as a brave mystical knight. Concurrently, he is quoting the books of chivalry‘s funeral processions and the curiosity of the occasional knight who wants to glance at the dead body. Furthermore, we see how extremely conversant the novelist is with the religious genre of spiritual chivalry, strongly opposed to the loose fantasy of the books of chivalry. Unable to look at St. John’s relic, an authentic knight of the heavenly militia, Don Quixote seems to silently acknowledge that there are higher chivalries than his own that he will never reach. No wonder he ends the adventure with a sad countenance, gaining a new identity as the “Caballero de la Triste Figura”.
