Input: As where to guard the walls, full many a foss Begirds some stately castle, sure defence Affording to the space within, so here Were model'd these; and as like fortresses E'en from their threshold to the brink without, Are flank'd with bridges; from the rock's low base Thus flinty paths advanc'd, that 'cross the moles And dikes, struck onward far as to the gulf, That in one bound collected cuts them off. Such was the place, wherein we found ourselves From Geryon's back dislodg'd. The bard to left Held on his way, and I behind him mov'd. On our right hand new misery I saw, New pains, new executioners of wrath, That swarming peopled the first chasm. Below Were naked sinners. Hitherward they came, Meeting our faces from the middle point, With us beyond but with a larger stride. E'en thus the Romans, when the year returns Of Jubilee, with better speed to rid The thronging multitudes, their means devise For such as pass the bridge; that on one side All front toward the castle, and approach Saint Peter's fane, on th' other towards the mount.
"Which way did the naked sinners come?" is "Sinners came from hitherward"?
