The Life of Cesare Borgia — Rafael Sabatini

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.
