In the city of Canosa di Puglia the procession of the Desolate is an ancient rite, among the most evocative of Holy Week in Puglia. On the Saturday before Easter, hundreds of women dressed in black and with their arms intertwined accompany the procession of the Desolate Virgin, singing the high-pitched song of the "Stabat Mater", a prayer written by Jacopone da Todi.
