In this review of Colin J. Humphreys, 'The Mystery of the Last Supper: Reconstructing the Final Days of Jesus', William R Telford points out that the non-astronomical parts of Humphrys' argument are based on the assumption that the chronologies described in the New Testament are historical and based on eyewitness testimony. In doing so, Telford says, Humphreys has built an argument upon unsound premises which "does violence to the nature of the biblical texts, whose mixture of fact and fiction, tradition and redaction, history and myth all make the rigid application of the scientific tool of astronomy to their putative data a misconstrued enterprise."
