The term ‘clarion’ comes from the Latin term ‘clario’, which denotes a trumpet (this, in turn, is related to the Latin ‘clarus’, which means clear and bright). In the mediaeval period, clarions were distinctly smaller and higher-pitched instruments than trumpets. In The Canterbury Tales (c. 1387–1400), Geoffrey Chaucer references a clarion in a list of instruments used to initiate battle (see the first tale, titled, The Knight’s Tale).

The idiomatic expression is often said to have arisen early in the 19th century. However, it can be traced to at least as early as 1787. In a lyrical poem published that year, titled, ‘Ode for the New Year,’ Warton and Parsons wrote:

In rough magnificence array’d
When ancient Chivalry display’d
The pomp of her heroic games;
And crested chiefs, and tissued dames,
Assembles, at the clarion’s call
In some proud castle’s high-arch’d hall…

See The Gentleman’s Magazine, January 1787, p. 68.
