No day without a line, was the advice and the practice of Apelles. No one must expect to be perfect in any art, without incessant care and diligence; therefore, "Nulla dies abeat, quin linea ducta supersit," no day should be suffered to pass, without leaving some memorial of itself. "Diem perdidi," "I have lost a day," was the exclamation of the Emperor Titus, finding, on a review of what had been performed, that he had relieved no distressed person, not done any act deserving recollection in the course of the day.
