Bound & free (Cunningham)

In the thirtieth year of life
I took my heart to be my wife,

And as I turn in bed by night
I have my heart for my delight.

No other heart may mine estrange
For my heart changes as I change,

And it is bound, and I am free,
And with my death it dies with me.

J. V. Cunningham, "Epigram #1"
