Can anyone recommend some readings on this subject? I'm open to both introductory and exhaustive reading. Would prefer scholarly articles though, since in where I live there seems to be little interest in this subject; it might be a bit difficult to get a book (while it's easier to get access to articles via uni library)... but if anyone knows a good book, please still do share!
I really appreciate the help!
Peter Brown's works on late antiquity (for instance "The World of Late Antiquity") cover much of this material, although he touches upon the Syrian region but is not exclusively focused on it.
Likewise the Oxford guide to late antiquity has an entry entitled "Syriac and the 'Syrians'" which is online.
You might also find the books of Glen Bowersock and Garth Fowden useful.
It's less that there'e little interest in the subject than that "Late Antiquity" is sort of a specialized field and most of the books I'm familiar with approach it holistically rather than in regards to a particular region.
