A sceptre (or scepter in American English) is a staff or wand held in the hand by a ruling monarch as an item of royal or imperial insignia, signifying sovereign authority.
The Was and other types of staves 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 (the "shepherd's crook").
The sceptre also assumed a central role in the Mesopotamian world, and was in most cases part of the royal insignia of sovereigns and gods. This continued throughout Mesopotamian history, as illustrated in literary and administrative texts and iconography. The Mesopotamian sceptre was mostly called ĝidru in Sumerian and ḫaṭṭum in Akkadian.
The Biblical Book of Genesis refers to the sceptre of Judah.
“The sceptre shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh come; and unto him shall the gathering of the people be.”
In the First Persian Empire, the Biblical Book of Esther mentions the sceptre of the King of Persia.
"When the king saw Esther the queen standing in the court, she obtained favor in his sight; and the king held out to Esther the golden scepter that was in his hand. So Esther came near, and touched the top of the scepter."
Among the early Greeks, the sceptre (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.
