It originates from the ancient Greek wars, where the fiercest battles were fought between Greek city-states. The phrase emphasizes the intensity and skill involved in these conflicts.
Here's a breakdown of why this idiom arose:
* Constant Conflict: Ancient Greece was characterized by frequent warfare between city-states.
* Skillful Warriors: Greek hoplites, the heavily armed infantry, were renowned for their tactical brilliance and physical prowess.
* Internal Rivalries: Battles between Greek cities were particularly fierce due to cultural and political rivalries.
Therefore, the saying "where Greek met Greek" became a shorthand for a highly competitive and challenging situation.
The idiom is still used today to describe situations where individuals or groups with similar abilities and determination clash, regardless of their actual ethnicity.
