An Anglo-Saxon riddle

My breast is puffed up and my neck is swollen.
I've a fine head and a waving tail;
Ears and eyes also but only one foot ...
Scourged by the rainlash, I stand alone.
I'm bruised by heavy batteries of hail;
Hoar-frost attacks and snow half-hides me.
I must endure all this, not pour out my misery.

- the Benedictional of St. Aethelwold, c990AD
