I noticed a major shift from more realistic sculptures of Greco-Roman period during this time, the content during this period seems to be more important. This can be attributed to the shift in the church and the amount of influence it had over society.
The content of this time was very church oriented and very restrictive, almost a devolution of art in a way. Looking back at previous periods where human proportions and form were at the top of an artists list, it seems like the quality took a back seat to the narrative of the piece.
