(23) Most Bibles published during the Middle Ages contain a section devoted to genealogical tables showing the descent of humanity from Father Adam to the advent of Jesus Christ. The tree growing from the roof of the Ark represents the body of Noah and its three branches, his sons--Shem, Ham, and Japheth. The nations by the descendents of Noah's three sons are appropriately shown in the circles upon the branches of the tree. While such tables are hopelessly incorrect from a historical point of view, to the symbolist their allegorical interpretations are of inestimable importance.
