The earliest masonic texts each contain some sort of a history of the craft of masonry. The oldest known work of this type, The Halliwell Manuscript, also known as Regius Poem, dates from between 1390 and 1425. This document has a brief history in its introduction, stating that the "craft of masonry" began with Euclid in Egypt, and came to England in the reign of King Athelstan (born about 894, died 27 October 939). Shortly afterwards, the Cooke Manuscript traces masonry to Jabal, son of Lamech (Genesis 4: 20–22), and tells how this knowledge came to Euclid, from him to the Children of Israel (while they were in Egypt), and so on through an elaborate path to Athelstan. This myth formed the basis for subsequent manuscript constitutions, all tracing masonry back to biblical times, and fixing its institutional establishment in England during the reign of Athelstan (927–939).
