As we discussed the ways in which altarpieces changed during the Renaissance, the differences in what was portrayed were especially interesting. While in general polyptychs with many small, separated images were replaced by larger and more prominent works with fewer panels, the methods in which this was achieved differed greatly. Structural changes such as using a single image or a main image with a predella are the most obvious at first glance. However, the differences in iconography between areas was striking. An interesting example of this was the depiction of the Holy Trinity, which is affected by the beliefs of the patron and the location in which the art was meant to be placed. This resulted in vastly differing portrayals, with artists having to creatively adapt to those requirements.
