The humour was a surprise. It's a bit obvious, but Kenneth Williams' famous "Infamy! Infamy! They've all got it in for me!" sprang to mind.
Byron didn't intend it to ever be staged, so it seemed a bit of a shame to bring the curtain down as they're lighting the pyre. Mishima has a poor dear trapped in a burning carriage for the last half hour of his "Hell Screen".
"Salemenes: empower me with thy signet
To quell the machinations, and I lay
The heads of thy chief foes before thy feet.
Sardanaplaus: The heads — how many?
Salemenes: Must I stay to number
When even thine own's in peril? Let me go;
Give me thy signet—trust me with the rest.
Sardanapalus: I will trust no man with unlimited lives.
When we take those from others, we nor know
What we have taken, nor the thing we give."
"Sardanapalus: Come, Myrrha, let us go on to the Euphrates:
The hour invites, the galley is prepared,
And the pavilion, decked for our return,
In fit adornment for the evening banquet,
Shall blaze with beauty and with light, until
It seems unto the stars which are above us
Itself an opposite star; and we will sit
Crowned with fresh flowers like—
Myrrha:Victims."
"Arbaces: This woman's warfare
Degrades the very conqueror. To have plucked
A bold and bloody despot from his throne,
And grappled with him, clashing steel with steel,
That were heroic or to win or fall;
But to upraise my sword against this silkworm,
And hear him whine,it may be—
Beleses: Do not deem it:"
"Sardanapalus: My sword! O fool, I wear no sword: here, fellow,
Give me thy weapon. [To a Guard.]
[Sardanapalus snatches a sword from one of the soldiers,]"
"Sardanapalus: Be silent. — Guilt is loud. If ye are loyal,
Ye are injured men, and should be sad, not grateful.
Beleses: So we should be, were justice always done
By earthly power omnipotent; but Innocence
Must oft receive her right as a mere favour."
"Sardanapalus:Jove! — aye, your Baal —
Ours also has a property in thunder,
And ever and anon some falling bolt
Proves his divinity, — and yet sometimes
Strikes his own altars.
Myrrha: That were a dread omen.
Sardanapalus: Yes — for the priests."
"Sardanapalus: Fill full! why this is as it should be: here
Is my true realm, amidst bright eyes and faces
Happy as fair! Here sorrow cannot reach.
Zames: Nor elsewhere — where the King is, pleasure sparkles."
"Sardanapalus: Tell him to spare his person for the present,
And that I will not spare my own—and say,
I come.
Pania: There's victory in the very word."
"Sardanapalus: I am spent: give me a seat.
Salemenes: There stands the throne, Sire.
Sardanapalus: Tis no place to rest on,
For mind nor body: let me have a couch,
A peasant's stool, I care not what: so—now
I breathe more freely.
Salemenes: This great hour has proved
The brightest and most glorious of your life.
Sardanapalus: And the most tiresome."
"Sardanapalus:We have lived asunder
Too long to meet again — and now to meet!
Have I not cares enow, and pangs enow,
To bear alone, that we must mingle sorrows,
Who have ceased to mingle love?"
"Myrrha:: Why
Dwells thy mind rather upon that man's name
Than on his mate's in villany?
Sardanapalus: The other
Is a mere soldier, a mere tool, a kind
Of human sword in a friend's hand; the other
Is master-mover of his warlike puppet;
But I dismiss them from my mind. — Yet pause,
My Myrrha! dost thou truly follow me,
Freely and fearlessly?
Myrrha: And dost thou think
A Greek girl dare not do for love, that which
An Indian widow braves for custom?"
"Sardanapalus: In this blazing palace,
And its enormous walls of reeking ruin,
We leave a nobler monument than Egypt
Hath piled in her brick mountains, o'er dead kings,
Or kine — for none know whether those proud piles
Be for their monarch, or their ox-god Apis:
So much for monuments that have forgotten
Their very record!"
