Rafael Sabatini 
The Life of Cesare Borgia [EPUB ebook] 

This is no Chronicle of Saints. Nor yet is it a History of Devils. It is a record of certain very human, strenuous men in a very human, strenuous age; a lustful, flamboyant age; an age red with blood and pale with passion at white-heat; an age of steel and velvet, of vivid colour, dazzling light and impenetrable shadow; an age of swift movement, pitiless violence and high endeavour, of sharp antitheses and amazing contrasts. To judge it from the standpoint of this calm, deliberate, and correct century—as we conceive our own to be—is for sedate middle-age to judge from its own standpoint the reckless, hot, passionate, lustful humours of youth, of youth that errs grievously and achieves greatly. So to judge that epoch collectively is manifestly wrong, a hopeless procedure if it be our aim to understand it and to be in sympathy with it, as it becomes broad-minded age to be tolerantly in sympathy with the youth whose follies it perceives. Life is an ephemeral business, and we waste too much of it in judging where it would beseem us better to accept, that we ourselves may come to be accepted by such future ages as may pursue the study of us.
