Quartana there presides; a meagre fiend
Begot by Eurus, when his brutal force
Compress’d the slothful Naiad of the fens. 130
From such a mixture sprung this fitful pest,
With feverish blasts subdues the sick’ning land:
Cold tremors come, and mighty love of rest,
Convulsive yawnings, lassitude, and pains
That sting the burden’d brows, fatigue the loins, 135
And rack the joints, and every torpid limb;
Then parching heat succeeds, till copious sweats
