The Raven Song

I saw
Three ravens
Yesterday
One stayed
Behind
Two flew
Away
Which one
Remained
I cannot
Say
One stayed
Behind
Two flew
Away
Alone before
The mystery
Of time
I dived
And found
A creature of
The sea
She stole
Upon me
From behind
And swam
Away
Ahead of me
I saw
Three ravens
Yesterday
One stayed
Behind
Two flew
Away
Which one
Remained
I cannot
Say
One stayed
Behind
Two flew
Away
