Symbols are very often objects or designs or photographs and consciously and unconsciously play a part in representing something which is usually far more significant than the symbol itself.
Each nation has its symbols and the best known is often the flag of the country itself but there are many others. In the case of our monarchy some of the best known are the crown, the profile image of the monarch (e.g. on the $5 note), the Queen's personal coat of Arms (see SOVEREIGN), the orb and sceptre and sword of state, the mace used in parliament. The list is a long one but each item used in a particular place or instance symbolises the authority of the monarch within that field e.g. in parliament, in law courts, in council chambers, on Commonwealth government stationery etc. The sub-menus above list some of the more important ones.
