Why do very few Greek paintings exist today?
The great majority of the works of art produced in ancient Greece and Rome no longer survive. Paintings have rotted, crumbled or burned. Marble statues were smashed or perished in medieval lime-kilns.
Do any ancient Greek paintings survive?
Due to the perishable nature of the materials used and the major upheavals at the end of antiquity, not one of the famous works of Greek panel painting has survived. We have slightly more significant survivals of mural compositions.
When did ancient Greek art end?
Ancient Greek art spans a period between about 900 and 30 BCE and is divided into four periods: Geometric, Archaic, Classical, and Hellenistic.
Why do we not have many Roman frescoes?
The primary reason is that paintings in the Greco Roman era were mainly murals and frescoes painted as decorations in mansions, palaces, and temples etc, so they weren't portable and couldn't be moved to safety should there be a need to. The paintings only lasted as long as the buildings.
