Inferno

Name: Inferno
Author: Dante Alighieri

Dante Alighieri Original title Inferno (Italian, 1304)

Inferno is the first part of Italian writer Dante Alighieri's 14th-century epic poem Divine Comedy. It is followed by Purgatorio and Paradiso. The Inferno tells the journey of Dante through Hell, guided by the ancient Roman poet Virgil. In the poem, Hell is depicted as nine concentric circles of torment located within the Earth; it is the "realm ... of those who have rejected spiritual values by yielding to bestial appetites or violence, or by perverting their human intellect to fraud or malice against their fellowmen". As an allegory, the Divine Comedy represents the journey of the soul toward God, with the Inferno describing the recognition and rejection of sin.

“Here sighs and lamentations and loud cries
were echoing across the starless air,
so that, as soon as I set out, I wept.
Strange utterances, horrible pronouncements,
accents of anger, words of suffering,
and voices shrill and faint, and beating hands—
all went to make a tumult that will whirl
forever through that turbid, timeless air,
like sand that eddies when a whirlwind swirls.”

“And one his limb transpierced, and one lopped off, should show, it would be nothing to compare with the disgusting mode of the ninth Bolgia. A cask by losing centre-piece or cant was never shattered so, as I saw one rent from the chin to where one breaketh wind. Between his legs were hanging down his entrails; his heart was visible, and the dismal sack that maketh excrement of what is eaten. While I was all absorbed in seeing him, he looked at me, and opened with his hands his bosom, saying: "See now how I rend me; How mutilated, see, is Mahomet; in front of me doth Ali weeping go, cleft in the face from forelock unto chin; and all the others whom thou here beholdest, disseminators of scandal and of schism while living were, and therefore are cleft thus.”

Henry Powell Spring in 1944; popularized by John F. Kennedy misquoting Dante (24 June 1963) http://www.bartleby.com/73/1211.html. Dante placed those who "non furon ribelli né fur fedeli" [were neither for nor against God] in a special region near the mouth of Hell; the lowest part of Hell, a lake of ice, was for traitors.
According to the John F. Kennedy Presidential Library & Museum http://www.jfklibrary.org/Research/Research-Aids/Ready-Reference/JFK-Quotations.aspx President Kennedy got his facts wrong. Dante never made this statement. The closest to what President Kennedy meant is in the Inferno where the souls in the ante-room of hell, who "lived without disgrace and without praise," and the coward angels, who did not rebel but did not resist the cohorts of Lucifer, are condemned to continually chase a banner that is forever changing course while being stung by wasps and horseflies.
See Canticle I (Inferno), Canto 3, vv 35-42 for the notion of neutrality and where JFK might have paraphrased from.
