The South Transept contains the Pillar of Angels, a massive supporting pillar for the ceiling. It is composed of an octagonal pillar surrounded by four engaged columns, which reach upwards to support the vaults, and four slender colonettes. It is decorated with four vertical groups of statue-columns, depicting scenes from Christ and the Last Judgement, as well as four angels carrying the instruments of the Passion, and above that, four more angels sounding trumpets. At the lower level are statues of the four Evangelists. The pillar was created in the middle of the 13th century, most probably by a group of sculptors from France or Burgundy. Other parts of the vaults are upheld by Atlantes, supports in the form of human figures.
