According to Jan Morris ("Spain", p. 33), Alcalá del Ebro is the fictional Isla Barataria which Sancho Panza ruled in Don Quixote.
In a letter, Don Quixote gives Sancho provincial advice on governorship gleaned from the romances he has read, thought to have been inspired by the Diálogo de Mercurio y Carón attributed to Alfonso de Valdés. Quixote's simplistic and romantic understanding of government may have been the author using the allegorical ínsula to satirize the lack of practical learning on the part of philosopher-doctors' placed in positions of power.
