War, and a correspondence was invented between the king of Troy and the king of Israel, in which the latter excuses himself for not coming to join the Trojan army. It was in the beginning of the twelfth century that a famous professor of the university of Paris called Petrus Comestor wrote his _Historia Scholastica_, which for all the Middle Ages served as the text-book of Biblical history. But, like the mediæval aspect of the world, so the history of the world was not purely Biblical. The Bible always had to suffer the strong rivalry of apocryphal and legendary fiction. Already the Jews had invented a life of Adam, full of miraculous events, which appealed to the taste of the average man much more than the simple and severe story of the Bible itself; the lives of Abraham, of Moses, of Solomon were enriched in the same way. Christianity continued this kind of fancy. The story of the holy root was traced back into paradise; it was a branch from the tree of life, given to Adam's son Seth and planted by him on his father's tomb. It had been used as a bridge over the Kidron until the queen of Sheba arrived at Jerusalem. Being a prophetess, she worshipped this holy root; consequently Solomon tried to use it in his temple, but the carpenter did not succeed in cutting it to the necessary length; therefore it lay unused, "rejected by the builders," until the time came when a tree was wanted to crucify Jesus; so Jesus died--on the cross which was the tree of life--a splendid symbolism, indeed, but set forth in a strange legend. Or they investigated the earlier history of the thirty pieces of silver given to Judas Iscariot as the reward for the betrayal of his master, tracing the money back as far as Abraham. The life of Christ was surrounded by apocryphal legends of all kinds: the story of his birth and of his childhood; his stay in Egypt; how in their flight lions and all kinds of wild beasts accompanied the holy family; how a palm-tree bowed down before them in order to provide them with its fruits; how at Jesus' arrival in Egypt all the idols of the Egyptians fell down; how he helped his father Joseph in his carpenter shop; and so on. Again the miracles at his death, the descent to hell, the resurrection and ascension, everything was covered with an abundance of miraculous narratives, partly enlargements, developments of the canonical accounts, partly mere fiction. In addition to this apocryphal life of Jesus there is the life of the Virgin, giving a most curious description of her birth and childhood and again of her death, making every detail parallel to the life of Christ himself and yet keeping hers subordinate. The mediæval life of Christ begins--one may say--with the birth of Mary (or with the story of her parents, Joachim and Anna) and ends with the death and assumption of Mary. The history of the apostles as read in this period is nearly all apocryphal except the few data taken from the canonical book of Acts. Then the history of Christianity
