The legendary battle between the over-grown Philistine warrior Goliath and the humble shepherd boy David is an archetype which has resonance well beyond the Old Testament account.

The defiant courage of the underdog appeals to our deep-seated emotional need to witness the powerless turning the tables, for once, on the powerful.
