Sculpture commissioned by the Church or Royalty was primarily composed of the best money could buy. Bronze, granite, marble, porphyry, limestone, ivory and gold. They were used to decorate the portals of the great Gothic Cathedrals. Usually the westward facing portal was decorated first and then over the years the northern and southern facing portals would add sculptures. Consequently, the styles on the western portals were more simply Gothic, whereas the northern portals featured the High Gothic, or more sophisticated works. The statues were decidedly more human, more life like, borrowing facial expression and posture from the Ancient Greeks whereas works preceding the Gothic period were stiffer and less naturalistic. Artists such as Claus Sluter as late as the 14th Century, would take this naturalistic bent all the way to a photo-realism, a absolute mirror on real life, with such glorious works as Mary with Child, preserved in the Louve in Paris. The detail is remarkable, down to the last fingernail, and sly half-smiles. Though with this caliber of excellence there of course came critics, one of whom declared the baby Jesus appeared an adult in miniature, instead of an infant.
