What is the origin of 'Music soothes the savage beast'?

The actual phrase in modern English is:

"Music has Charms to soothe a savage Breast"

The phrase was coined by the Playwright/Poet William Congreve, in The mourning bride, 1697:

ACT I. SCENE I.

A Room of State. -

The Curtain rising slowly to soft Music, discovers ALMERIA in Mourning, LEONORA waiting in Mourning. -

After the Music ALMERIA rises from her Chair, and comes forward. -

ALM. Music has Charms to sooth a savage Breast,

To soften Rocks, or bend a knotted Oak.

I've read, that things inanimate have mov'd,

And, as with living Souls, have been inform'd,

By Magic Numbers and persuasive Sound.

What then am I? Am I more senseless grown

Than Trees, or Flint? O force of constant Woe!

'Tis not in Harmony to calm my Griefs.

Anselmo sleeps, and is at Peace; last Night

The silent Tomb receiv'd the good Old King;

He and his Sorrows now are safely lodg'd

Within its cold, but hospitable Bosom.

Why am not I at Peace?
