O mystery of love!  O strange romance! 
Among the Peers and Paladins of France,
Shining in steel, and prancing on gay steeds,
Noble by birth, yet nobler by great deeds,
The Princess Emma had no words nor looks
But for this clerk, this man of thought and books.

The summer passed, the autumn came; the stalks
Of lilies blackened in the garden walks;
The leaves fell, russet-golden and blood-red,
Love-letters thought the poet fancy-led,
Or Jove descending in a shower of gold
Into the lap of Danae of old;
For poets cherish many a strange conceit,
And love transmutes all nature by its heat.

No more the garden lessons, nor the dark
And hurried meetings in the twilight park;
But now the studious lamp, and the delights
Of firesides in the silent winter nights,
And watching from his window hour by hour
The light that burned in Princess Emma’s tower.

At length one night, while musing by the fire,
O’ercome at last by his insane desire,—­
For what will reckless love not do and dare?—­
He crossed the court, and climbed the winding stair,
With some feigned message in the Emperor’s name;
But when he to the lady’s presence came
He knelt down at her feet, until she laid
Her hand upon him, like a naked blade,
And whispered in his ear:  “Arise, Sir Knight,
To my heart’s level, O my heart’s delight.”

And there he lingered till the crowing cock,
The Alectryon of the farmyard and the flock,
Sang his aubade with lusty voice and clear,
To tell the sleeping world that dawn was near. 
And then they parted; but at parting, lo! 
They saw the palace courtyard white with snow,
And, placid as a nun, the moon on high
Gazing from cloudy cloisters of the sky. 
“Alas!” he said, “how hide the fatal line
Of footprints leading from thy door to mine,
And none returning!” Ah, he little knew
What woman’s wit, when put to proof, can do!

That night the Emperor, sleepless with the cares
And troubles that attend on state affairs,
Had risen before the dawn, and musing gazed
Into the silent night, as one amazed
To see the calm that reigned o’er all supreme,
When his own reign was but a troubled dream. 
The moon lit up the gables capped with snow,
And the white roofs, and half the court below,
And he beheld a form, that seemed to cower
Beneath a burden, come from Emma’s tower,—­
A woman, who upon her shoulders bore
Clerk Eginhard to his own private door,
And then returned in haste, but still essayed
To tread the footprints she herself had made;
And as she passed across the lighted space,
The Emperor saw his daughter Emma’s face!
