Bagdad,1253. That day somebody went to the market the same,
Though it was different from any other day
People were not different from any other people.
The silence was under the mosque with the columns around and the round dome,
A grave was monumental with a square base and a pinnacle above.
The shouts were not breaking the fixity
As the tumultuous clattering and clanging of the Mongolian cavalry.
The crumbling local system fell under the sabres,
Their cut lasted a short time, then another boring power lasted a long.

Paolo Giuseppe Mazzarello
