Caerwent No. 2 / Caer went / Venta Siluru / Venta Silurum

There is an entry for Caerwent in the Domesday survey [https://opendomesday.org/place/ST4690/caerwent/] [accessed 13 September 2020] but it mentions neither cleric nor church in it. Rees (2003) writes: "a Saxon font has an inverted Roman column for its base". Rees (ibid.) also mentions "a Christian community here [i.e., in Caerwent] in Roman times, and evidence of two house churches has been found". The present font at St. Tathan's, however, does not appear 'Saxon' at all, unless it has been re-cut, nor is it raised on anything resembling a Roman column; the font consists of an octagonal basin with a rounded underbowl which ends i a double moulding, and a polygonal pedestal base of 17th or 18th-century making at the earliest. The Archaeologia cambrensis (5th Series, vol. II, no. VIII, October 1885: 329) reports on a visit to the church "dedicated to St. Stephen", but no mention is made of any font in it; "There is a holy water stoup in the north wall, close by the door". The entry for this church in the CADW [http://cadwpublic-api.azurewebsites.net/reports/listedbuilding/FullReport?lang=en&id=2014] [accessed 13 September 2020] notes: "This church appears to be C13 in origin although a pre-Norman church is recorded at Caerwent, also a possible early Christian congregation during the Roman period; but there is no evidence that either of these shared the same site as the present church. [...] There are two fonts, only the first, that by the door, is native to this church. It is a re-cut Norman tub on a baluster pedestal, probably early C18 in its present form. The second font in the south aisle is also Norman in origin, but has been introduced to this church from the destroyed church at Dinham about 2 km to the north of Caerwent. It is a tub type on an unrelated plain base."
