"Não é fácil descortinar em Portugal outro mais grandioso e espectacular...
A Terra é verde e o céu é azul; é tudo verde e azul com raras pintas brancas do casario, que mais do que moradias de homens parecem janelas da própia paisagem.
Nas noites de luar, quando o grande balão de oiro surge na lomba das montanhas, o vale enche-se de magia, dum sortilégio que paira desde os píncaros longínquos ís águas sussurrantes do Caima.
De manhã é o milagre, todos os dias há um milagre de luz sobre a terra quando o sol nasce em Vale de Cambra."

— Ferreira de Castro

"A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself. For the traitor appears not a traitor; he speaks in accents familiar to his victims, and he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murderer is less to fear. The traitor is the plague."

- Marcus Tullius Cicero
