The use of chiaroscuro emphasizes the three-dimensionality of the figure, drawing the viewer's eye to her serene expression.

The dimensions are approximately 100 x 150 cm, making it a significant work in size. Francisco de Zurbarán was known for his religious paintings, often focusing on saints and martyrs.
