The glories of our blood and state
Are shadows, not substantial things;
There is no armour against fate;
Death lays his icy hand on kings:
Scepter and crown
Must tumble down,
And, in the dust, be equal made
With the poor crooked scythe and spade.

James Shirley (1596–1666) English poet, playwright

Contention of Ajax and Ulysses for Achilles’s Armour, sc. 3, st. 1 (1659)
    (Source)

Sung by Calchas over the body of Ajax.

The poem was eventually set to music by Edward Coleman. It was said to be a favorite of England's King Charles II, perhaps because it was said by some to have terrified Oliver Cromwell.

Titled as "Death's Final Conquest" in Thomas Percy, Reliques of Ancient English Poetry, Book 3, No. 2 (1885). There the first line is given as "birth and state."
