The churches of West Mersea, in Essex, and Wroxeter, in Salop, are believed to stand on sites of Roman villas; a little contributory testimony is afforded by the fact that the shaft of the font, in each case, is fashioned from the drum of a Roman column[16]. In the case of Wroxeter, however, the only tessellated pavement recorded by Professor Haverfield was found a little to the north of the church. The conditions are supposed to have been similar at Haydon and Chollerton, in Northumberland, and at Great Salkeld, in Cumberland; in all of these instances the fonts are said to be hollowed out of Roman altars[17]. During the rebuilding of St Swithin’s Church, Lincoln (A.D. 1880-88), a Roman altar (Fig. 1) was discovered beneath the tower. The old fabric belonged to the Decorated period, while the altar dates from the second century of the Roman occupation. There is thus an intervening space of more than a thousand years, and this gap cannot yet be actually bridged over. At the deserted church of Widford, in Oxfordshire, portions of a Roman tessellated pavement were found in the chancel[18]. Professor Seebohm, who closely studied the district around Hitchin, and discovered strong proofs of unbroken occupation of village sites, gives some interesting examples which bear on our subject. He thinks that the church of Much Wymondley, near that town, stands within a Roman holding, probably that of a retired veteran[19]. A Roman cemetery was discovered hard by, and to the east of the church is a double “tumulus,” which Professor Seebohm conjectured to be a “toot-hill,” or a terminal mound[20]. These toot-hills will be again mentioned; meanwhile, we are bound to notice that more recent investigators claim this particular hillock as an early castle-mound. Nevertheless, it is stated that the mound and its associated bailey-court have been [Illustration: FIG. 2.
