No peace by day, no sleep at night I take,
Since these brave chiefs assembled for my sake.
With cold indifference may'st thou look down,
For no man's safety anxious but thy own;
But I, the least solicitous for mine,
Feel for this friend's, that comrade's, and for thine.
Much shall I feel for all this martial band,
Unless they safe regain their native land.

Lines 811–818; Jason to Tiphys. - Argonautica (3rd century BC) - Book II
