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..."

From a small spark, Great flame has risen.

Reason flies When following the senses, on clipped wings.

Love can move the Sun and the stars.

Into the eternal darkness, into fire and into ice.

Love and the gentle heart are but the same thing.

From a little spark may burst a flame.
