The Devil's Dictionary: Inauspiciously

A Roman slave appeared one day
Before the Augur. "Tell me, pray,
If —" here the Augur, smiling, made
A checking gesture and displayed
His open palm, which plainly itched,
For visibly its surface twitched.
A denarius (the Latin nickel)
Successfully allayed the tickle,
And then the slave proceeded: "Please
Inform me whether Fate decrees
Success or failure in what I
To-night (if it be dark) shall try.
Its nature? Never mind — I think
'Tis writ on this" — and with a wink
Which darkened half the earth, he drew
Another denarius to view,
Its shining face attentive scanned,
Then slipped it into the good man's hand,
Who with great gravity said: "Wait
While I retire to question Fate."
That holy person then withdrew
His scared clay and, passing through
The temple's rearward gate, cried "Shoo!"
Waving his robe of office. Straight
Each sacred peacock and its mate
(Maintained for Juno's favor) fled
With clamor from the trees o'erhead,
Where they were perching for the night.
The temple's roof received their flight,
For thither they would always go,
When danger threatened them below.
Back to the slave the Augur went:
"My son, forecasting the event
By flight of birds, I must confess
The auspices deny success."
That slave retired, a sadder man,
Abandoning his secret plan —
Which was (as well the craft seer
Had from the first divined) to clear
The wall and fraudulently seize
On Juno's poultry in the trees.
