1. What is it?

Hubris is the notion of ‘foolish pride’ in which pride leads to one’s downfall. In Greek mythology it is a level of arrogance that is seen to challenge the gods, sparking their anger and causing them to react.

The consequence of hubris is ‘the fall’ in which the proud individual is knocked down.

Technically hubris relates to the pride, not the fall, but mostly people consider it a fall caused by pride.

3. Examples in literature

Ozymandias 
by Percy Bysshe Shelley

I met a traveller from an antique land
Who said: “Two vast and trunkless legs of stone
Stand in the desert. Near them on the sand,
Half sunk, a shattered visage lies, whose frown
And wrinkled lip and sneer of cold command
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them and the heart that fed.
And on the pedestal these words appear:
‘My name is Ozymandias, King of Kings:
Look on my works, ye mighty, and despair!’
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare,
The lone and level sands stretch far away”.

Paradise Lost 
by John Milton

Excerpt from Book 1:

From their Creator, and transgress his Will
For one restraint, Lords of the World besides?
Who first seduc’d them to that foul revolt?
Th’infernal Serpent; he it was, whose guile
Stirr’d up with Envy and Revenge, deceiv’d
The Mother of Mankind, what time his Pride
Had cast him out from Heav’n, with all his Host
Of Rebel Angels, by whose aid aspiring
To set himself in Glory above his Peers,
He trusted to have equall’d the most High,
If he oppos’d; and with ambitious aim
Against the Throne and Monarchy of God
Rais’d impious War in Heav’n and Battle proud
With vain attempt. Him the Almighty Power
Hurl’d headlong flaming from th’Ethereal Sky
With hideous ruin and combustion down
To bottomless perdition, there to dwell
In Adamantine Chains and penal Fire,
Who durst defy th’Omnipotent to Arms.
