This glass, when made, was, by the workman's skill, <br />The sum of sixty minutes to fulfil. <br />Time, more nor less, by it will out be spun, <br />But just an hour, and then the glass is run. <br />Man's life we will compare unto this glass, <br />The number of his months he cannot pass; <br />But when he has accomplished his day, <br />He, like a vapour, vanisheth away.<br /><br />John Bunyan<br /><br />http://www.poemhunter.com/poem/upon-the-hour-glass/
