Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ The successful practice of sculpture and painting requires that the mind should be vigorous, free, and unencumbered, as it is at the age when the blood still dances; it demands that the spirit should act with an ardent will, yet restrained within just limits, and, above all, determined to remain unfettered by the pleasures of the world; he who cannot practise abstinence, or at least temperance, as regards those pleasures, let him not attempt the study of any art or science whatsoever, seeing that such delights can never be made to accord with the requirements of study. ”
