‘Tis not the balm, the sceptre and the ball,
The sword, the mace, the crown imperial,
The intertissued robe of gold and pearl,
The farced title running ‘fore the king,
The throne he sits on, nor the tide of pomp
That beats upon the high shore of this world,
No, not all these, thrice-gorgeous ceremony,
Not all these, laid in bed majestical,
Can sleep so soundly as the wretched slave,
Who with a body filled and vacant mind
Gets him to rest, crammed with distressful bread.
– William Shakespeare
Henry V, Act 4, Scene 1.
