In 1915 he published El abuelo del rey (The King's grandfather), a novel that tells the story of three generations of a tiny Levantine town, for the sake of presenting, and not without a little irony, the struggle between tradition and progress, the pressures of one’s environment, and above all, a meditation about time.
One year later, Figuras de la Pasión del Señor (Characters from Our Lord Passion) (1916-17) was published, formed by a series of scenes about the last days of Jesus. Also in 1917, Miró began his autobiographical-style works with Libro de Sigüenza (Sigüenza's book), in which Sigüenza is not only the heteronym or alter-ego of the author, but the author's own lyrical self, which gives unity to the scenes which comprise the book. El humo dormido (The sleeping smoke) (1919), about time, and Años y leguas (Years and leagues) (1928), which again uses the character of Sigüenza as a protagonist, are of a similar nature.
In 1921, he finished two more books: El ángel, el molino, el caracol del faro (The angel, the mill, the lighthouse snail), a book of scenes, and the novel Nuestro padre San Daniel (Our father Saint Daniel), which is part of a series with El obispo leproso (The leprous bishop)(1926). Both play out in the Levantine city of Oleza, a reflection of Orihuela, in the last third of the 19th century. The city, submerged in lethargy, is seen as a microcosm of mysticism and sensuality, in which the characters debate between their natural inclinations and social repression, and intolerance and the religious resistance to progress to which they are submitted.
Ricardo Gullón has described the Miró's stories as lyrical novels. They pay more attention to the expression of feelings and sensations than the simple act of listing events. The hallmarks of Miró's work are:
Impermanence is the essential theme of the author, who incorporates the past into a continuing present, through sensations, evocation, and memory.
Like Azorín before him, the senses are a form of creation and knowledge in Miró's work, hence
