After invading southern Greece and receiving the submission of other key city-states, Philip turned his attention to Sparta and asked menacingly whether he should come as friend or foe. The reply was "Neither."Losing patience, he sent the message:
If I invade Laconia, I shall turn you out.
The Spartan ephors again replied with a single word:
If.
Philip proceeded to invade Laconia, devastate much of it, and eject the Spartans from various parts.
Sweet treat. Also makes me think of the work of Andy Goldsworthy, the Brit artist who makes images like this happen.
