Michelangelo made this as a wedding gift for the Florentine merchant Agnolo Doni and his wife Maddalena Strozzi — a tondo, a circular format favoured for domestic commissions.
It is the only completed easel painting by Michelangelo that survives.
Michelangelo considered himself primarily a sculptor and took on painting reluctantly.
The Sistine Chapel was four years away and he was still arguing with the Pope about it.
This shows what a sculptor does when he paints.
The Holy Family twists in an interlocking spiral of impossible grace and physical power.
Mary's arm, passing the infant over her shoulder, is the arm of an athlete.
The muscles of the Christ child are those of a small Hercules.
The whole composition has mass.
You feel it would be heavy to lift.
In the background, behind the Holy Family, a group of nude young men lean on a low wall.
They are separated from the sacred scene by a ledge.
Who they represent is unresolved — pagans not yet reached by Christianity, figures from classical antiquity, or simply a formal device Michelangelo used to fill the space.
The answer, if there is one, Michelangelo took with him.
Fun fact: the original carved frame is also in the Uffizi, attributed to Michelangelo himself.
If the attribution is correct, it may be the only surviving example of an artist-designed Renaissance frame.
