A scene from the Maestà altarpiece, depicting Christ washing the feet of his disciples with characteristic Sienese grace and linear precision.

This panel is a component of the Maestà, the monumental altarpiece commissioned for the Siena Cathedral. Duccio di Buoninsegna depicts the biblical narrative of Christ washing the feet of his disciples, an act of humility performed before the Last Supper. The composition is structured within a shallow, architectural space, typical of the Sienese approach to perspective during the early fourteenth century.

Christ is positioned on the left, kneeling before Peter, who sits upon a raised bench. The disciples are grouped to the right, their expressions and gestures conveying a sense of quiet observation and contemplation. Duccio employs a refined colour palette, utilising muted tones for the garments, which contrast with the gold leaf halos and the architectural elements of the room. The figures are rendered with a focus on linear grace and emotional clarity, characteristics that define the artist's contribution to the transition from Byzantine traditions toward a more humanistic style of representation.

The spatial arrangement is defined by the wooden beams of the ceiling and the bench, which provide a sense of order to the scene. The inclusion of small, specific details, such as the basin and the sandals, grounds the narrative in a tangible reality. This work demonstrates the technical precision of tempera painting, where layers of pigment are applied to create subtle gradations of light and shadow. The focus remains on the interaction between the figures, capturing a moment of theological significance through a balanced and measured visual language. As a piece from the Maestà, it reflects the high level of craftsmanship associated with the Sienese workshops of the period, offering a clear view into the devotional art of the early Italian Renaissance.
