Is this it?
"The Eagle's Flight
For the hunterís fright, Eagleís talons command,
While the Eagleís heights abound the flight.
For the hunterís smile, the Eagleís pasts remind;
In Eagleís might, smiles the hunterís fright.
The Eagle could not; all its commands keep held,
If the Eagleís hunter too wore some talons,
For its smiles forever come to mock the foe fled,
In scared hunters, since times ago in ages.
For to the mighty Eagle, talons are rewarding,
In the flights high, talons well persevere,
And in the Eagleís shadows cast, its will to spring
More ladders, the Eagle to shove higher.
The Eagleís talons will not for a day go blunt,
For its scratches will them, keep sharp,
And the broken ones, victims will surely meant
While witnesses will be playing the harp."
Then I don't know to which work you're referring.
