How did Fra Filippo Lippi use perspective in Annunciation and Two Donors?

In his work Annunciation and Two Donors (c. 1440), Fra Filippo Lippi utilized the newly developed principles of linear perspective to organize the composition in a novel way.1

Rather than relying solely on traditional methods, Lippi integrated these mathematical perspective techniques with skillful contrasts between color and form to create a sense of spatial depth. This approach allowed him to structure the scene with greater rational clarity, effectively guiding the viewer's eye through the architectural setting. Furthermore, the painting is noted for its sensitive rendering of movement—particularly in the light garments of the two figures at the door—which adds a dynamic quality to the space and anticipates the expressive style of his student, Sandro Botticelli.12
