Roman Catholic churches are sometimes found to have unorthodox alinements, but not so generally as is commonly believed. Frequently, the so-called lack of orientation simply means that the position of the altar is reversed. Thus, St George’s Cathedral, in Westminster, like St Peter’s at Rome, has its altar at the West end. But since the axis in these cases, as in that of the little Anglican church at Well, previously mentioned, lies East and West, I prefer to consider these churches as not fundamentally violating the rule. To this matter we must presently return. It has been asserted, and afterwards stoutly denied, that disregard of orientation, with respect to the Eastern altar, is a feature of the churches of the Jesuits[489]. A goodly number of modern churches owe their incorrect alinements to the limitations of shape, slope, and area of the ground on which the buildings are placed. Thus, while the old parish church of Hornsey, Middlesex, stands correctly, the new building is sadly discordant. This variation is caused by a corresponding difference in the long axis of the rectangular plot on which it is built. The axis of the Roman Catholic church of the English Martyrs at Streatham, again, is in marked disagreement with that of the Anglican parish church hard by; a glance at the manner in which the former edifice is wedged in seems to supply the reason. Whether the North-to-South line of the Church of the Oratory, Brompton, is to be so explained, is more uncertain. Of ancient English buildings which do not orientate, the classic example is found at the Cistercian Abbey of Rievaulx, Yorkshire. A steep bank on the one side of the church, and a river on the other, necessitated an axis from North to South. Then we have to deal with churches designedly mis-built. The Puritan Sir Walter Mildmay, founder of Emmanuel College, Cambridge, built the original College chapel North and South, as a protest against superstition, and in marked derogation of catholic usage (A.D. 1584). This action led Evelyn to speak of “that zealous house” which was “reformed _ab origine_[490].” The Cambridge example is serviceable as showing the approximate date when early tradition began to be defied.
