Formally identified by the inscription "OLIMBRIUS REX AMTIOCHIE", Olibrius, the prefect of Antioch, is a relatively rare figure in 12th-century iconography, as artists typically focused more on episodes from the martyrdom of Saint Margaret.
The choice of a column statue here, at the same scale as certain major figures in medieval liturgy, is exceptional and unprecedented, and could be explained by the didactic use of the cloister sculptures, where part of the religious education for the canon school was likely carried out. This column statue is unique because its name and title are engraved on the phylactery, leaving no doubt about its identification. The other figures were likely identified by their phylacteries, which were probably painted.
