In addition to rediscovering and studying the writings of ancient Greeks and Romans, the humanists dug up archaeological sites to find artworks and learn about ancient Roman architecture.
(This was surprisingly easy because they were living in the very cities that had once been the heart of the Roman Empire.) Soon painters and architects were reviving “classical” styles. Popular features of ancient Roman architecture, such as columns with capitals, rounded arches with a keystone on top, and large domes, were used in new buildings. Unlike the helter skelter cityscapes of the medieval period, Renaissance buildings were constructed symmetrically, with one side looking the same as the other.
