<u>Relief is a technique of sculpturing in which elements are on the solid background, unattached from it, while in-the-round sculptures are completely three-dimensional and unattached. </u>
<u>When we see the west portal on the Cathedral of St Lazare, we see it is a relief done in the round and attached to the wall behind it. </u>
We can see that it is exactly sunken relief as it is done in the<u> low relief technique, with the sunken area, which means elements do not rise above the original level of the flat surface, </u>
