Shield and spear, seen from front Shield is in foreground on right hand side, spear diagonally backwards over far shoulder Shield and spear, seen from rear Shield is in foreground on left hand side, spear diagonally forwards Scepter (or spear), seen from front Spear is on far shoulder (regardless of the direction that the bust is facing). Often detailing, such as a gorgon, will be placed on the chest.
