The Virgin, sitting with her arm resting on the crib, supports the Child asleep on her lap, wrapping him in the white sheet. The work takes its title from the straw protruding from the manger, which together with the presence of the donkey and the ox recalls the theme of the Nativity and makes the scene something more than a simple Madonna and Child. The image is in fact interwoven with multiple references to the Passion of Christ: Jesus is lying on his mother's knees, as in the Pietà, wrapped in a sheet, just as he will remain for three days in the shroud; on the right, the wooden planks nailed and crossed, could allude to the Crucifixion; and the ears that sprout on the left recall the sacrifice of the Eucharist. All this explains the Virgin's worried and veiled gaze of sadness. Although similar symbolic allusions to the passion motif are not uncommon in such a subject, in this case we wanted to capture in the sad atmosphere of the painting a personal memory of the death of Van Dyck's sister, Cornelia, which led to the definitive return of the artist. in Antwerp after his stay in Italy.
