The Moving finger....

 Omar Khayyám, the famous Persian astronomer, mathematician and poet was born on 18 May 1048.
 
For some strange reason, we own two copies of his poetic tome, The Rubáiyát of Omar Khayyám, although scholars disagree on the origins of this work.
Hardly surprising given that he was born 971 years ago.
 
The first verse is so evocative and conjures up an immediate image
 
 
AWAKE! for Morning in the Bowl of Night
Has flung the Stone that puts the Stars to Flight:
And Lo! the Hunter of the East has caught
The Sultan’s Turret in a Noose of Light.
 
It is however, well into the poem, that is the most well known in my eyes
 
The Moving Finger writes; and, having writ,
Moves on: nor all thy Piety nor Wit
Shall lure it back to cancel half a Line,
Nor all thy Tears wash out a Word of it.
 
I know all this sounds a bit pompous, but after all, it is Silly Saturday.
