LOVE THE LIGHT-GIVER.

Veggio co' bei vostri occhi.

With your fair eyes a charming light I see,
For which my own blind eyes would peer in vain;
Stayed by your feet the burden I sustain
Which my lame feet find all too strong for me;
Wingless upon your pinions forth I fly;
Heavenward your spirit stirreth me to strain;
E'en as you will, I blush and blanch again,
Freeze in the sun, burn 'neath a frosty sky.
Your will includes and is the lord of mine;
Life to my thoughts within your heart is given;
My words begin to breathe upon your breath:
Like to the moon am I, that cannot shine
Alone; for lo! our eyes see nought in heaven
Save what the living sun illumineth.

Michelangelo Buonarroti
