This is an Old Spanish verse form. The word Ovillejo means tight little bundle. The last line is a "redondilla," a "little round" that collects all three of the short lines. The rhyme scheme and the pattern are established (see below), but the meter is at the poet's discretion, although in Spanish the longer lines tend to be octosyllabic. (octosyllabic: A line of verse containing eight syllables)

Example #1

Foreboding

We're splintering like weathered wood,
No good
Against the storm; the final sum
Can come
To nothing but a dying kiss.
Of this
I'm certain now. We're all there is,
And as I watch us fall apart
A cold foreboding stirs my heart:
No good can come of this.

Example #2

Wolfrider Cub

The sky is double-mooned and starred;
It's hard
To look away from that dark deep
To sleep.
Although by day the sun is bright,
At night
The darkness seems to sharpen sight.
And in the brilliance it brings,
My wolf blood shines, it scents, it sings:
It's hard to sleep at night.
