Sete anos de pastor Jacob servia Labão, pai de Raquel, serrana bela; Mas não servia o pai, servia a ela, E a ela só por prémio pretendia. - Luís de Camões

Nem eu delicadezas vou cantando
Co'o gosto do louvor, mas explicando
Puras verdades já por mim passadas.
Oxalá foram fábulas sonhadas!

I was long ago undeceived that protesting
could bring redress. But whoever suffers
is bound to complain if the pain is great.
So I did! But the cry that could offer
relief is itself feeble and exhausted,
and it is not through weeping that pain abates.

Great Sir, let never the astonished Gall
The English, German, and Italian,
Have cause to say, the fainting Portugal
Could not advance the great work he began.
Let your advisers be experienced all,
Such as have seen the world, and studied man.
For, though in science much contained be,
In special cases practice more doth see.
