The mystery of Mary's physical ascent into heaven was a favorite theme during the Counter-Reformation, when the Catholic church was reaffirming its devotion to the Virgin. In its sensuous beauty and dramatic appeal, Juan de Valdés Leal's depiction characterizes the baroque style at its most operatic.
Amidst spiraling forms, swirling draperies, and extravagant gestures, the figure of Mary, arms outstretched, is borne aloft on the wings of a robust group of angels, while a choir of less corporeal angels makes music in the background. The excitement of the supernatural event is sustained by the varied poses and dramatic gestures of the animated figures gathered around the tomb below. Saint Paul, closest to us, shields his eyes against the radiant light.
Utilizing a popular device of baroque painting, Valdés Leal placed the monumental figures of two of the apostles in the foreground to lead the eye into the composition and to establish a sense of scale. In this instance, their position also serves to create the impression that, like the viewer, they have just come upon the scene from a point outside the picture space.
Renowned for his vivacious brushwork, Valdés Leal was also a superb colorist, whose pale but vibrant palette anticipated the decorative tones of the rococo style of the eighteenth century.
