Just one quote by Omar Khayyam
Omar Khayyám (born 1048 AD, Neyshapur, Persia—1131 AD, Neyshapur, Iran), was a Persian polymath, mathematician, philosopher, astronomer, physician, and poet. He also wrote treatises on mechanics, geography, and music.
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.
