There was almost no science, no medicine in this time; the world seemed to be full of miracles having no rational connection with one another. There was no causality, no law of nature. This was exactly the same view that we have in most parts of the Bible. Therefore people did not feel any difficulty in identifying their own notions about miracle and nature with the Biblical ones. Nay, we may say that many of the legendary miracle stories are copied after Biblical patterns. Even the wording is often modelled according to Biblical phraseology. "Healing all manner of disease and all manner of sickness," from Matt. 9 : 35, is repeated in many a saint's life. Bible history in the embellished form which we have just now observed inspired mediæval art. In the first place, there were the inner walls of the churches, usually painted from top to bottom. If we remember that a Romanesque church had only very small windows, we understand what a large space was given to painting. Pictures are the text-book for those who cannot read; so Pope Gregory the Great had said, and this dictum was repeated many a time. It is true, of course. These plain mural paintings, awkward as they often are, make a greater impression on a simple mind than even the best written account could produce. The art is nothing but illustration; the painter tries to bring before the people who view his work the main features of the Biblical text. One must, indeed, know the text in order to understand the pictures. Sometimes the spectator is helped by additional inscriptions. To the illiterates these may be read and explained by the priest; and then even the simplest peasant will understand and always remember the story. Some churches were decorated in this way twice or even oftener, the first painting being covered with lime and whitewashed and then another painting being put upon it, according to the style of the later time. Here, again, we see the Biblical history, pure and plain at the beginning, but by and by combined with motives taken from the apocryphal sources and the lives of the saints. At the annunciation the angel meets the Virgin Mary at a well; it is to his mother Mary that the risen Christ appears before he reveals himself to his disciples.
