A. A fragment, apparently that of a Roman temple or basilica, near the church of St. Nicholas at Leicester, which contains horizontal courses of brick at intervals, and arches constructed of brickwork; the curious portion of a wall of similar construction, with remains of brick arches on the one side, which indicate it to have formed part of a building, and not a mere wall as it now appears, at Wroxeter, Salop; and the polygonal tower at Dover Castle, which, notwithstanding an exterior casing of flint, and other alterations effected in the fifteenth century, still retains many visible features of its original construction of tufa bonded with bricks at intervals. Roman masonry, of the mixed description of brick and stone, regularly disposed, is found in walls at York, Lincoln, Silchester, and elsewhere; and sometimes we meet with bricks or stone arranged herring-bone fashion, as in the vestiges of a Roman building at Castor, Northamptonshire, and the walls of a Roman villa discovered at Littleton, Somersetshire. Q. Have we any remains of the ancient British churches erected in this country in the third, fourth, or fifth centuries? A. None such have yet been discovered or noticed; for the ruinous structure at Perranzabuloe in Cornwall, which some assert to have been an ancient British church, is probably not of earlier date than the twelfth century; and the church of St. Martin at Canterbury, built in the time of the Romans, which Augustine found on his arrival still used for the worship of God, was rebuilt in the thirteenth century, but, to all appearance, with the same materials of which the original church was constructed. Q. Do any of our churches bear a resemblance to Roman buildings? A. The church now in ruins within the precincts of the Castle of Dover presents features of early work approximating Roman, as a portal and window-arches formed of brickwork, which seem to have been copied from those in the Roman tower near adjoining; the walls also have much of Roman brick worked up into them, but have no such regular horizontal layers as Roman masonry displays. The most ancient portions of this church are attributed to belong to the middle of the seventh century. The church of Brixworth, Northamptonshire, is perhaps the most complete specimen we have existing of an early Anglo-Saxon church: it has had side aisles separated from the nave by semicircular arches constructed of Roman bricks, with wide joints; these arches spring from square and plain massive piers. There is also fair recorded evidence to support the inference that this church is a structure of the latter part of the seventh century. Roman bricks are worked up in the walls, in no regular order, however, but indiscriminately, as in the church at Dover Castle. [Illustration: Pilaster Rib-work Arch, Brigstock Church.] Q. What peculiarities are observable in masonry of Anglo-Saxon construction?
