A bit more Omar Khayyam

'Tis all a Chequer-board of Nights and Days
Where Destiny with Men for Pieces plays:
Hither and thither moves, and mates, and slays,
And one by one back in the Closet lays.

The Ball no Question makes of Ayes and Noes,
But Right or Left, as strikes the Player goes;
And He that toss'd Thee down into the Field,
He knows about it all – He knows – He knows!

These are the 2 verses before that posted by Kendall.

... and of course:

And when Thyself with shining Foot shall pass
Among the Guests Star-scatter'd on the Grass
And in thy joyous Errand reach the Spot
Where I made one - turn down an empty Glass!
