Love insists the loved loves back

Now you know how much my love for you burns deep in me when I forget about our emptiness, and deal with shadows as with solid things.

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..."

The whole universe is but the footprint of the Divine goodness.

Justice divine has weighed: the doom is clear. All hope renounce, ye lost, who enter here.

Go right on and listen as thou goest.

To course across more kindly waters now my talent's little vessel lifts her sails, leaving behind herself a sea so cruel; and what I sing will be that second kingdom, in which the human soul is cleansed of sin, becoming worthy of ascent to Heaven.
