Thomas Babington Macaulay Quote

Lars Porsena of Closium
By the Nine Gods he swore
That the great house of Tarquin
Should suffer wrong no more.
By the Nine Gods he swore it,
And named a trysting day,
And bade his messengers ride forth,
East and west and south and north,
To summon his array.

Horatius, st. 1 - Lays of Ancient Rome (1842)
