There are two portraits of Pope Innocent X connected to the Spanish painter Diego Velázquez, who painted them around 1650 during his trip to Rome. The two works are closely related because the smaller portrait was likely a preparatory study for the larger and more famous painting.
The small portrait shows the pope in a simpler and more direct way. It is painted quickly and focuses mainly on capturing the pope’s face, expression, and character. Velázquez probably used it to study how Innocent X looked while sitting for him. The brushwork is loose, and the painting feels more like an experiment or first attempt.
The larger portrait, which is the famous one in the gallery, is a finished and more formal work. In it, Innocent X sits in a chair wearing rich red robes, surrounded by deep red fabric. Velázquez refined the details and composition, but he kept the strong psychological realism he discovered in the smaller study. The pope’s sharp eyes and serious expression make the portrait feel very lifelike.
Because of this relationship, many scholars believe the small painting helped Velázquez prepare for the final portrait. It allowed him to observe the pope closely and develop the powerful, realistic image that appears in the larger masterpiece.
