The image of La Madonna del Parto (English: Our Lady of Parturition) is a religious depiction of the Blessed Virgin Mary as pregnant which was popularised in Tuscany, Italy during the 14th—century.
Notable examples include works by Taddeo Gaddi, Bernardo Daddi and Nardo di Cione, but the fresco by Piero della Francesca in the Museum of Monterchi, in the province of Arezzo, is considered the most famous one. The Madonna was portrayed standing, alone, often with a closed book on her stomach, an allusion to the Incarnate Word. These works were associated with the devotions of pregnant women, praying for a safe delivery.[1]
Sometimes, as with a statue by Sansovino in the Basilica of Sant'Agostino in Rome, the depiction is of a Virgin and Child, which was however known as a Madonna del Parto, because it was especially associated with devotions related to pregnancy.
Herein the Virgin Mary wears the Girdle of Thomas, a belt of knotted cloth cord that was a relic held in Prato Cathedral, which many versions show her wearing.
