Frist of all nice topic. As a Turk, the meaning of close city charmed me 
Beroea was made a Macedonian city by Seleucus Nicator between 301 and 281 B.C. It was sacked by Chosroes in A.D. 540.
But region is Chalybonitis
Roman Map 194 AD
East Roman Map 400 AD
And Chosroes / Khosrow ( 540 AD?)
But I don't think Muslim used the name Boreoea after the conquest of North Syria, so I believe that Muslim changed it name just after the conquest.
However I believe that Byzantine source used the old name for a while.
Western source accept name Aleppo but not Arabic name of Damascus (Ash-Sham), this is also interesting.
