For over a century, biblical scholars have agreed that parts of the synoptic gospels (Matthew, Mark and Luke) are picked up from a previous source-a lost gospel, which is popularly called Q (from the German word Quelle which means source).

The Q-hypothesis rests on very solid grounds and most scholars accept it. This book tells us all about it. It also discusses some unresolved questions (such as: Was Q written in Aramaic or Greek?).

The reconstruction of Q, the lost gospel, is a challenging and formidable task. Using various critical literary methods, leading scholars have undertaken the work, and the reconstruction work of the German scholar Athanasius Polag is a major achievement. The author has enhanced and clarified his book by translating Polag's reconstruction of Q.
