Ho, trumpets, sound a war-note!
Ho, lictors, clear the way!
The Knights will ride, in all their pride,
Along the streets to-day.
To-day the doors and windows
Are hung with garlands all,
From Castor in the Forum,
To Mars without the wall.
Each Knight is robed in purple,
With olive each is crowned;
A gallant war-horse under each
Paws haughtily the ground.
While flows the Yellow River,
While stands the Sacred Hill,
The proud Ides of Quintilis
Shall have such honor still.
Gay are the Martian Kalends,
December's Nones are gay,
But the proud Ides, when the squadron rides,
Shall be Rome's whitest day.

And all the people trembled,
And pale grew every cheek;
And Sergius the High Pontiff
Alone found voice to speak:
"The gods who live forever
Have fought for Rome to-day!
These be the Great Twin Brethren
To whom the Dorians pray.
Back comes the chief in triumph,
Who, in the hour of fight,
Hath seen the Great Twin Brethren
In harness on his right.
Safe comes the ship to haven,
Through billows and through gales,
If once the Great Twin Brethren
Sit shining on the sails.
Wherefore they washed their horses
In Vesta's holy well,
Wherefore they rode to Vesta's door,
I know, but may not tell.

Here, hard by Vesta's temple,
Build we a stately dome
Unto the Great Twin Brethren
Who fought so well for Rome.
And when the months returning
Bring back this day of fight,
The proud Ides of Quintilis,
Marked evermore with white,
Unto the Great Twin Brethren
Let all the people throng,
With chaplets and with offerings,
With music and with song;
And let the doors and windows
Be hung with garlands all,
And let the knights be summoned
To Mars without the wall:
Thence let them ride in purple
With joyous trumpet-sound,
Each mounted on his war-horse,
And each with olive crowned;
And pass in solemn order
Before the sacred dome,
Where dwell the Great Twin Brethren
Who fought so well for Rome."
