Martin Anstey was a Bible chronologer significant for his contribution to biblical literalism for successfully resolving the apparent time gaps contained within the Bible's internal chronology. In 1913 Anstey's thesis, 'The Romance of Bible Chronology' was published, explaining how subtle pieces of information within the Bible text resolve these apparent chronological gaps. He was the brother of John Anstey and also a keen 'Anstey' genealogist, mapping many of the early branches of the Devon Ansteys.
