from On the Infinite Universe and Worlds (DE L'INFINITO UNIVERSO ET MONDI)
by GIORDANO BRUNO 1548 – 17 February 1600 burned at the stake in Rome's Campo de' Fiori
THREE SONNETS
Passing alone to those realms The object erst of thine exalted thought, I would rise to infinity: then I would compass the skill Of industries and arts equal to the objects. There would I be reborn: there on high I would foster for thee Thy fair offspring, now that at length cruel Destiny hath run her whole course Against the enterprise whereby I was wont to withdraw to thee. Fly not from me, for I yearn for a nobler refuge That I may rejoice in thee. And I shall have as guide A god called blind by the unseeing. May Heaven deliver thee, and every emanation Of the great Architect be ever gracious unto thee: But turn thou not to me unless thou art mine.
Escaped from the narrow murky prison Where for so many years error held me straitly, Here I leave the chain that bound me And the shadow of my fiercely malicious foe Who can force me no longer to the gloomy dusk of night. For he who hath overcome the great Python With whose blood he hath dyed the waters of the sea Hath put to flight the Fury that pursued me. To thee I turn, I soar, O my sustaining Voice; I render thanks to thee, my Sun, my divine Light, For thou hast summoned me from that horrible torture, Thou hast led me to a goodlier tabernacle; Thou hast brought healing to my bruised heart.
Thou art my delight and the warmth of my heart; Thou makest me without fear of Fate or of Death; Thou breakest the chains and bars Whence few come forth free. Seasons, years, months, days and hours -- The children and weapons of Time -- and that Court Where neither steel nor treasure avail Have secured me from the fury [of the foe]. Henceforth I spread confident wings to space; I fear no barrier of crystal or of glass; I cleave the heavens and soar to the infinite. And while I rise from my own globe to others And penetrate ever further through the eternal field, That which others saw from afar, I leave far behind me

Giordano's crime was to envisage the Earth as being one of many inhabited worlds and the Sun as one of many stars.
