The Poets pass the Gate of Hell and are immediately assailed by cries of anguish. Dante sees the first of the souls in torment. They are the opportunists, those souls who in life were neither for good nor evil but only for themselves. Mixed with them are those outcasts who took no sides in the Rebellion of the Angels. They are neither in Hell nor out of it. Eternally unclassified, they race round and round pursuing a wavering banner that runs forever before them through the dirty air; and as they run they are pursued, by swarms of wasps and hornets, who sting them and produce a constant flow of blood and putrid matter which trickles down the bodies of the sinners and is feasted upon by loathsome worms and maggots who coat the ground.
