Aramaic Sources of Mark's Gospel is a book by Maurice Casey, who is a reader in early Jewish and Christian studies at the University of Nottingham.
Casey takes four passages from the Book of Mark and reconstructs what an original written Aramaic source would have said if the Book of Mark was a translation of that source.
[1] Chapter 1 is a review of prior investigations of the Aramaic substratum of the Gospels.
[1] Chapter 2 describes Casey's methodology for reconstructing the possible Aramaic sources behind the synoptic Gospels.
In particular, he relies on the written Aramaic found in the contemporaneous Dead Sea Scrolls.
