Sorrowful words become the sorrowful; angry words suit the passionate; light words a playful expression; serious words suit the grave.
[Lat., Tristia maestum
Vultum verba decent; iratum, plena minarum;
Ludentem, lasciva: severum, seria dictu.]
They change their sky, not their mind, who cross the sea. A busy idleness possesses us: we seek a happy life, with ships and carriages: the object of our search is present with us.
Whatever you teach, be brief; what is quickly said, the mind readily receives and faithfully retains, everything superfluous runs over as from a full vessel.
And yet more bright
Shines out the Julian star,
As moon outglows each lesser light.
[Lat., Micat inter omnes
Iulium sidus, velut inter ignes
Luna minores.]
The poets aim is either to profit or to please, or to blend in one the delightful and the useful. Whatever the lesson you would convey, be brief, that your hearers may catch quickly what is said and faithfully retain it. Every superfluous word is spilled from the too-full memory.
