Europe was in a cold spell from the end of the Roman period. In fact it may have been the cause of the end of the Roman empire. Late Antique Ice Age lasted from ~400 -> ~900 AD.
People were barely surviving. There was no excess produce to fuel the population growth which would allow professions like artist or sculptor on any kind of scale.
On the contrary, there were famines, disease, plagues, unrest and population migrations.
It was only the recovery of the climate which allowed farm produce to improve, populations to grow during the medieval period, then you get art, cathedrals and so on.
