At this period the Saxon refugees were followed into Scotland by large numbers of Norman knights. These were well received by King David and presented with lands in the outlying districts, which he had subdued, as well as throughout the country. The number and extensive possessions of these Norman immigrants are most apparent in the names of the proprietors settled in every part of the country.[54] The policy of colonising the outlying and turbulent districts with these trained knights is apparent. They would in self-defence help to keep the country in order, and defend it from the attacks of the still unsubdued regions of the North and West. It also had the effect of facilitating the spread of the Roman ecclesiastical system which the king had so much at heart. The country, being parcelled out in the hands of Anglo-Normans already imbued with the principles and practices of that system, would soon be brought into conformity with it. Each proprietor would, as soon as possible, raise a hamlet round his castle for his retainers, and a village church for their religious requirements. Thus there speedily arose, instead of the ancient tribal arrangements, a new distribution of the land into parishes, each with its parochial church and priest, and each tithed to its own manor. Evidences of these early parish churches still survive in many places, and they will be illustrated in the sequel. But “this goodly framework of a parochial secular establishment was shipwrecked when scarcely formed.”[55] Monachism was then in the ascendant in Europe. New Orders were constantly being created, to spread the banner of Roman supremacy. Their monasteries soon drew to themselves all that was worth having in the Church. The Lords encouraged them and presented them with lands and churches, and the people were attracted by their zeal and asceticism. They soon became rich and were able to indulge their taste in the erection of noble monasteries and churches, the illustration of which, erected during the three succeeding centuries, forms a most important part of the following pages. Having traced the course of the influences which affected the primitive ecclesiastical structures of Scotland till the period when the Irish influence was superseded by that of Rome, it is now proposed to glance shortly at the origin and development of the Norman style which, as we have seen, was introduced into this country in the twelfth century, and of the various styles of Gothic architecture which succeeded it. ROMANESQUE ARCHITECTURE. After the fall of the Roman empire in the fifth century, a debased style founded on Roman models prevailed over Western Europe, and [Illustration: FIG. 13.--Roman Arch--Pont du Gard.]
