White Horse

But thou, Goddess, farewell, and turn thy steeds to the Ocean stream,
And I will endure my misery still, even as I have borne it.
Farewell, bright-faced Selene; and farewell too, ye stars,
That follow the slow-moving chariot of the tranquil Night.

—Theocritus, Idylls.

Pictured above: head of a chariot horse belonging to the moon-goddess Selene, designed by Pheidias in marble, once situated on the east pediment of the Parthenon in Athens, now at the British Museum.

If

My favorite example of Laconic wit, as recounted by Plutarch:

…when Philip [of Macedon] wrote thus to the Spartans: “If once I enter into your territories, I will destroy ye all, never to rise again”; they answered him with the single word, “If.”
