When Titans Clash

This poem was recently found on a repaired vase, perhaps of ancient origin. Or maybe written yesterday.
Beware when Titans clash
If you live on land below.
They stomp about most rash
And seldom watch where they go.

They seek more distant goals
With their heads above the clouds.
Their passions drive their souls;
Self-purpose their vision shrouds.

All focused on campaign,
They answer the challenge's call.
They will rule their domain,
Or, with all foes, they will fall.

Who they were ere the fight
Is lost in fog of battle.
The thought to do what's right
Gone in combative prattle.

Urge to win overwhelms,
Knocking over reasons why.
Power lust for the realms
Blinds the more foresighted eye.

What victory is won
In this heedless ruins' wake?
All that was is undone --
No prize left intact to take.

Oh, Titans, be at peace
Within that you now possess,
And leave our bits of Greece
Unflattened by your excess.
