The Iliad 10.87–101

so long as the breath abideth in my breast and my knees are quick. I wander thus, because sweet sleep settleth not upon mine eyes, but war is a trouble to me and the woes of the Achaeans. Wondrously do I fear for the Danaans, nor is my mind firm, but I am tossed to and fro, and my heart leapeth forth from out my breast, and my glorious limbs tremble beneath me. But if thou wouldest do aught, seeing on thee too sleep cometh not, come, let us go to the sentinels, that we may look to them, lest fordone with toil and drowsiness they be slumbering, and have wholly forgot their watch. The foemen bivouac hard by, nor know we at all whether haply they may not be fain to do battle even in the night.
