The incident of Christ taking leave of his mother is not mentioned in the Gospels but is told in the Pseudo-Bonaventura's Meditations on the Life of Christ. The present composition is an unusually elaborate development of theme. Christ stands at the right, with his right hand on his chest and his left pointing upwards, presumably indicating his heavenly father's will. In the sky above Christ is God the Father, seated on clouds, and three angels bearing the instruments of the Passion; the Cross and hammer; the spear, the reed with the sponge and nails; and the column and flails. In the foreground, opposite Christ, stands the Virgin Mary. She is weeping as she contemplates Christ's future. In the sky immediately above her head a child angel holds the crown of thorns and a dagger or short sword, presumably referring to Simeon's prophecy to her: 'Yea, a sword shall pierce through thy own soul also.' (Luke 2.35).
