Claudio Guillen, a modern critic, has noted that time is also a unifying factor in this novel. Early incidents are told in detail, and at moments of pain specific amounts of time are measured ("I felt the pain from its horns for three days"). When Lazarillo is taken in by the squire his hunger pangs become so great that he begins to count the hours. But as conditions improve for Lazarillo's stomach, he gradually forgets about the slow passage of time. In fact, time now begins to race past: four months with the pardoner, four years with the chaplain. This slow, then swift, passage of time is used by Guillen to explain the extreme brevity of some later chapters of the novel. It is a mature Lazaro, he says, who is telling the story and reflecting on his childhood. And we are really seeing the memory process of this older Lazaro who glosses over less important parts of his life and dwells on the moments that matter. Other critics have responded to the question of "finality" in the work; that is, is Lazarillo an incomplete novel or not? Francisco Rico believes the novel is complete, and that there is a "circular" structure to it all. He notes that the novel is addressed to a certain fictional character ("You": Vuestra merced), and that Lazarillo intends to tell this character "all the details of the matter," the "matter" apparently being the questionable relations between the archpriest and Lazarillo's wife. So there is a continuity from the beginning of the work through the details of Lazarillo's life, until the last chapter ("right up to now") where the "matter" itself, alluded to previously in the Prologue, is finally given in some detail.
