RELIGION
The agnostic religion of Greeks are full of myths. The Greek art manifests the fables and superstitions about nature, life and death and man’s daily life with their human-like Gods. The Greek artists focused on beauty and harmony in architecture, sculpture, painting, pottery, hand-made art pieces etc.
