Our Lady of the Pillar is one of the oldest Marian invocations. According to tradition, when the Mother of Jesus was still living in Jerusalem, Saint James the Greater saw her arrive in mortal flesh on the banks of the Ebro River, accompanied by a group of angels carrying a column.
The Apostle had been one of the first to travel to the western confines of Europe — the Iberian Peninsula, the finis terrae, then part of the Roman Empire — to preach the Gospel. St. James the Apostle was downcast by the difficult work and Mary Most Holy wanted to show her motherly care by appearing and encouraging him. According to the same tradition, St. James received from the Virgin the order to build a chapel in her honour in the place of the apparition.
Today the column of the apparition is preserved in the Basilica of Pilar in Saragossa, and visitors have venerated it throughout the centuries. The carving of the Virgin is not even forty centimetres high. Its lines are late Gothic, and by the way the tunic is buttoned, the belt with its buckle, the high waist and the shoes, it can be dated to the 15th century. The figure of the Baby Jesus does not follow the sculptural style of the Virgin and was undoubtedly added to the latter, either to complete it or, more probably, to replace a previous one that was destroyed or deteriorated. He holds a little bird in one hand and with the other he clings tightly to his Mother's mantle. The ensemble sits on the Pillar, which is a smooth jasper column covered with worked silver that (+except on the 2nd, 12th and 20th of each month) lights up with an embroidered mantle, which is changed daily.
