Then wilt thou be secure of the success.
For on their life no grievous burden lies
Who are well natured, temperate and wise;
But an inhuman and ill-tempered mind
Not any easy part in life can find.
Lords of the world have but of life their lease,
And this, too, if the lessor please, must cease.
The youngest, in the morning, are not sure
That till the night their life they can secure.
Sir I. Denham.
