A sceptre or scepter (see spelling differences) is a symbolic ornamental staff or wand held in the hand by a ruling monarch as an item of royal or imperial insignia. Figuratively, it means royal or imperial authority or sovereignty, either right or cruel. The ancient Indian work of Tirukkural dedicates a separate chapter each on the ethics of the right sceptre and the evils of the cruel sceptre.
The Was and other types of staffs were signs of authority in Ancient Egypt. For this reason, they are often described as "sceptres", even if they are full-length staffs. One of the earliest royal sceptres was discovered in the 2nd Dynasty tomb of Khasekhemwy in Abydos. Kings were also known to carry a staff, and Pharaoh Anedjib is shown on stone vessels carrying a so-called mks-staff. The staff with the longest history seems to be the heqa-sceptre, sometimes described as the shepherd’s crook.
The Bronze Age rulers of Mesopotamia are not regularly depicted with sceptres. However, in some instances, they are shown armed, with bow and arrow and occasionally a mace.
Use of a rod or staff as representing authority can be traced to the beginning of Classical Antiquity. Among the early Greeks, the sceptre (Ancient Greek: σκῆπτρον, skeptron, "staff, stick, baton") was a long staff, such as Agamemnon wielded (Iliad, i) or was used by respected elders (Iliad, xviii. 46; Herodotus 1. 196), and came to be used by judges, military leaders, priests, and others in authority. It is represented on painted vases as a long staff tipped with a metal ornament. When the sceptre is borne by Zeus or Hades, it is headed by a bird. It was this symbol of Zeus, the king of the gods and ruler of Olympus, that gave their inviolable status to the kerykes, the heralds, who were thus protected by the precursor of modern diplomatic immunity. When, in the Iliad, Agamemnon sends Odysseus to the leaders of the Achaeans, he lends him his sceptre.
