A. Though we can neither trace satisfactorily the exact period of its introduction, or even that of its final extinction, (for it appears to have merged gradually into the pure and unmixed pointed style of the thirteenth century,) we have perhaps no remains of this kind to which we can attribute an earlier date than that included between the years 1130 and 1140, unless we except the intersecting arches at St. Botulph’s, Priory Church, Colchester, which may be a few years earlier; and it appears to have prevailed, in conjunction or intermixed with the Norman style, from thence to the close of the twelfth century, and probably to a somewhat later period. [Illustration: Arcade, Christ Church, Oxford.] FOOTNOTES: [76-*] The figure of a fish, whence the form _vesica piscis_ originated, was one of the most ancient of the Christian symbols, emblematically significant of the word ἴχθυς,[TN-3] which contained the initial letters of the name and titles of our Saviour. The symbolic representation of a fish we find sculptured on some of the sarcophagi of the early Christians discovered in the catacombs at Rome; but the actual figure of a fish afterwards gave place to an oval-shaped compartment, pointed at both extremities, bearing the same mystical signification as the fish itself, and formed by two circles intersecting each other in the centre. This was the most common symbol used in the middle ages, and thus delineated it abounds in Anglo-Saxon illuminated manuscripts. Every where we meet with it during the middle ages, in religious sculptures, in painted glass, on encaustic tiles, and on seals; and in the latter, that is, in those of many of the ecclesiastical courts, the form is yet retained. Even with respect to the origin of the pointed arch, that _vexata quæstio_ of antiquaries, with what degree of probability may it not be attributed to this mystical form? It is indeed in this symbolical figure that we see the outline of the pointed arch plainly developed at least a century and half before the appearance of it in architectonic form. And in that age full of mystical significations, the twelfth century, when every part of a church was symbolized, it appears nothing strange if this typical form should have had its weight towards originating and determining the adoption of the pointed arch.--Internal Decorations of English Churches, British Critic, April, 1839. [79-*] The date of the _foundation_ of an abbey or church must not, however, be confounded with that of its actual _erection_, which was often many years later, and the only certain guide to which is the date of the _Consecration_.
