The Roman era of Church organisation superseded the Celtic; and with the Roman dominance came the architecture of the Anglo-Normans, whom the presence and policy of Margaret, saint and queen, attracted to Scotland. It developed itself, always with some national characteristics of its own, until the War of Independence broke off all friendly intercourse with England. Later came, in place of alliance with England, the alliance with France, which lasted till the Reformation, and left its mark on many of the pages of "The Great Stone Book," which chronicle for us the vicissitudes of the past, the days of peace and prosperity, of war and penury, of reviving national health and energy, of new combinations and ideas in politics and statecraft, of spiritual decay and carnal pride and ostentation. These annals can be deciphered by the patient student of the walls and cloisters of the ancient churches and religious houses. To the founders and the owners of the latter, and chiefly to the great orders of the Augustinians, the Benedictines, and the Cistercians, we owe many of our noblest remnants of the past--all of them unhappily ruined; for the popular violence of the sixteenth century raged more fiercely against the monasteries than against the cathedrals. To the Episcopal system of government, introduced under Margaret, we owe the bishops' churches or cathedrals. The life and thought of the Church at the present day, move far enough apart from either prelacy or monasticism to allow us to look at each with an impartial eye, and to consider whether in its abolition we have parted with aught that it would have profited the Church to retain.
