ten o'clock
what is better than light ! I have the sun , a friend who comes to visit me every day without the permission of the governor or the jailer 's company . He comes in at the window and traces in my room a square the shape of the window , and which lights up the hangings of my bed down to the border . This luminous square increases from ten o'clock till mid-day , and decreases from one till three slowly , as if , having hastened to come , it sorrowed at leaving me . When its last ray disappears , I have enjoyed its presence for four hours . Is not that sufficient ? I have been told that there are unhappy beings who dig in quarries , and laborers who toil in mines , and who never behold it at all . ''
