The column of flagellation to which Christ had been tied during the Scourging at the Pillar was made of marble (McNeely, 2015). Part of the column remained at the Basilica of the Holy Sepulcher and resides in the Franciscan Chapel (Mason, 2017). Another part of it was given to Giovanni, Cardinal di Colonna the Younger, by the king of Jerusalem during the Fourth Crusade. Colonna took it back with him to Rome, Italy, and placed it in the Basilica di Santa Prassede, his cardinalate church (McNeely, 2015). This part of the Column is housed in a bronze reliquary and can be found at the San Zeno Chapel.
Fragments of the column of flagellation have been distributed around the world throughout the centuries in ways similar to the True Cross. Above is a photograph of a small piece of the column in a sealed reliquary that comes from Rome.
 The Crusades were a series of nine religious wars that started in 1095 by order of Pope Urban II (Mills, 1820). These wars were carried out to recover the Holy Land and other sacred sites for Christianity from under Muslim rule, which had been in place since the 7th century. It was common practice during the Crusades to translate relics from the Holy Land to Rome and other places in the West for their ‘preservation’ (Andrea & Rachlin, 1992; McNeely, 2015).
