The Moving Finger Writes
The moving finger writes; and, having writ,
Moves on: Nor all your piety nor wit
Shall lure it back to cancel half a line
Nor all your tears wash out a word of it
(Omar Khayyam, 1048–1131)
بر لوحْ نشانِ بودنیها بودهاست،
پیوسته قلم ز نیک و بد فرسودهاست؛
در روز ازل هر آنچه بایست بداد،
غم خوردن و کوشیدنِ ما بیهوده است،
