Not to forget the real heroes of this world:
18th of August 2015
On his knees, he awaits his beheading.
This is Syrian archaeologist Dr. Khaled al-Asaad, chief of the excavations of Palmir (Palmyra). Khaled al-Asaad refused to reveal the location of the treasures and antiques of Tadmur (now Palmyra) that he hid before the arrival of the Islamic State.
Al-Asaad was beheaded in the square in front of the museum where he worked for over 50 years.
His mutilated body was then hung at a traffic light.
Khaled al-Asaad was the top guardian of Palmyra antiques and, in July 2015, he was captured by Islamic State fighters. Despite many tortures, he did not reveal the location of the museum’s treasures and was executed in the central square of Palmyre. When it became clear that fighters were going to capture Palmyre, scientists led by Al Asaad went to all lengths to hide Palmyre’s unique and invaluable antiques. He played a central role in saving hundreds of artifacts, transporting them from Palmyre to a safe location.
Khaled al-Asaad spoke five languages in addition to six ancient idiomatic languages, some of which are now extinct. Several European countries offered him residence and citizenship, but he refused to leave Syria.
He fought to his death to save the heritage of humanity.

Kaveh Akbar Palmyra after Khaled al-Asaad bonepole bonepole since you died there’s been dying everywhere do you see it slivered where you are between a crown and a tongue the question still more god or less I am all tangled in the smoke you left the swampy herbs the paper crows horror leans in and brings its own light this life so often inadequately lit your skin peels away your bones soften your rich unbecoming a kind of apology when you were alive your cheekbones dropped shadows across your jaw I saw a picture I want to dive into that darkness smell the rosewater the sand irreplaceable jewel how much of the map did you leave unfinished lthere were so many spiders your mouth a moonless system of caves filling with dust the dust thickened to tar your mouth opened and tar spilled out
I am an archeologist, I cann’t stop thinking about Khaled – al Asaad.
Requiescat in Pace, Brother.
