Here you will find the Poem Sestina of poet Dante Alighieri
I have come, alas, to the great circle of shadow, to the short day and to the whitening hills, when the colour is all lost from the grass, though my desire will not lose its green, so rooted is it in this hardest stone, that speaks and feels as though it were a woman. And likewise this heaven-born woman stays frozen, like the snow in shadow, and is unmoved, or moved like a stone, by the sweet season that warms all the hills, and makes them alter from pure white to green, so as to clothe them with the flowers and grass. When her head wears a crown of grass she draws the mind from any other woman, because she blends her gold hair with the green so well that Amor lingers in their shadow, he who fastens me in these low hills, more certainly than lime fastens stone. Her beauty has more virtue than rare stone. The wound she gives cannot be healed with grass, since I have travelled, through the plains and hills, to find my release from such a woman, yet from her light had never a shadow thrown on me, by hill, wall, or leaves? green. I have seen her walk all dressed in green, so formed she would have sparked love in a stone, that love I bear for her very shadow, so that I wished her, in those fields of grass, as much in love as ever yet was woman, closed around by all the highest hills. The rivers will flow upwards to the hills before this wood, that is so soft and green, takes fire, as might ever lovely woman, for me, who would choose to sleep on stone, all my life, and go eating grass, only to gaze at where her clothes cast shadow. Whenever the hills cast blackest shadow, with her sweet green, the lovely woman hides it, as a man hides stone in grass.
