This treatment of space consists of four main aspects&colon; centering, balancing, frontality, and depth. With Parthian art, on the contrary, frontality becomes the normal treatment of the figure. A typical feature of Parthian art is the frontality of the people shown. Frontality, the first principle, indicates that art was viewed directly from the front. Sam Byrne's characteristic treatment of crowds is to paint giving frontality to human figures. The style is characterised by strict frontality, and a distinctive style of hair and clothing. Frontality is a key feature of Ionic temples.
