Scourge

A scourge is a whip or lash, especially a multi-thong type, used to inflict severe corporal punishment or self-mortification on the back.

The word is most commonly considered to be derived from Old French escorgier - "to whip", going further back to the Vulgar Latin excorrigiare: the Latin prefix ex- "out, off" with its additional English meaning of "thoroughly", plus corrigia - "thong", or in this case "whip". Some connect it to Latin: 'excoriare', "to flay", built of two Latin parts, ex- ("off") and corium, "skin".

A scourge (Latin: flagrum; diminutive: flagellum) typically consists of several thongs fastened to a handle. A well known configuration of a scourge is the cat o' nine tails. The cat o' nine tails has two versions: the navy version is made of thick ropes with knotted ends, the army and civil prison versions are usually made of leather.

The scourge, or flail, and the crook are the two symbols of power and domination depicted in the hands of Osiris in Egyptian monuments. The shape of the flail or scourge is unchanged throughout history. However, when a scourge is described as a 'flail' as depicted in Egyptian mythology, it may be referring to use as an agricultural instrument. A flail was used to thresh wheat, not implement corporal punishment.

The priests of Cybele scourged themselves and others. Such stripes were considered sacred.

Hard material can be affixed to multiple thongs to give a flesh-tearing "bite". A scourge with these additions is called a scorpion. Scorpio is Latin for a Roman flagrum and is referred to in the Bible: 1 Kings 12:11: "...My father scourged you with whips; I will scourge you with scorpions" said Rehoboam, referring to increased conscription and taxation beyond Solomon's. The name testifies to the pain caused by the arachnid. Testifying to its generous Roman application is the existence of the Latin words Flagrifer 'carrying a whip' and Flagritriba 'often-lashed slave'. According to the Gospel of John, Pontius Pilate, the Roman governor of Judea, ordered Jesus to be scourged.
