The patron of this tondo is unknown but they are valid reasons for thinking that it has been commissioned by the Medici family. The two angels who hold the book are probably the two brothers Lorenzo the Magnificent and Giuliano.
This harmonious composition has been replicated several times in the master’s workshop. It has been acquired by the Uffizi in 1784.
The title of the work is inspired by the beginning of the prayer "magnificat anima mea" that the Christ Child is pointing. This is the canticle sung by Mary in praise of the Lord on her visit to Elizabeth, the wife of Zachariah, who is expecting a child.
On the left page of the book, we see Zachariah’s prophecy on the birth of his son John the Baptist (patron saint of Florence). A serene fluvial landscape can be seen in the background, while in the foreground other two angels are crowing the Virgin. She is dipping her pen in the inkwell as she writes; with the other hand she supports the Child and holds a pomegranate, the fruit of Paradise.
Botticelli adapted the sacred theme to the shape and the support, thus the figures appear as if reflected in a convex mirror.
