And here Dante describes an evidently spherical world... "The lamp of the world [the sun] rises to mortals through different passages; but through that which joins four circles with three crosses [the position of the rising sun at the vernal equinox] it issues with a better course and conjoined with better stars, and tempers and stamps the wax of the world more after its own fashion. Although such an outlet had made morning there and evening here, and all the hemisphere there was bright, and the other dark..."
Through me you pass into the city of woe: Through me you pass into eternal pain: Through me among the people lost for aye. Justice the founder of my fabric moved: To rear me was the task of power divine, Supremest wisdom, and primeval love. Before me things create were none, save things Eternal, and eternal I shall endure. All hope abandon, ye who enter here.
That infinite and indescribable good which is there above races as swiftly to love as a ray of light to a bright body.It gives of itself according to the ardor it finds, so that as charity spreads farther the eternal good increases upon it,and the more souls there are who love, up there, the more there are to love well, and the more love they reflect to each other, as in a mirror.
There sighs, lamentations and loud wailings resounded through the starless air, so that at first it made me weep; strange tongues, horrible language, words of pain, tones of anger, voices loud and hoarse, and with these the sound of hands, made a tumult which is whirling through that air forever dark, and sand eddies in a whirlwind.
