Christ Appears to the Apostles Behind Closed Doors (Maestà) is a tempera on panel painting by Duccio di Buoninsegna (1255–1260), created in 1308. Measuring 51 × 39 cm, it depicts the biblical scene from John 20:19-23. This painting is housed at Museo dell'Opera Metropolitana del Duomo, Piazza Duomo, 8, Siena.
This scene is on one of the back crowning panels of the Maestà.
The episodes Appearance Behind Locked Doors and Doubting St Thomas take place in the same surroundings, the house where the apostles took refuge for fear of the Jews. The door in the centre, firmly shut with a horizontal bar (a detail which emphasizes the miraculous nature of the event), frames and shows up the dominant figure of Christ, towards whom the two groups of apostles are converging.
