On the W wall of the tower is a Roman gravestone bearing the inscription:
DIS MANIBUS / NOMINI SACRI /BRUSCI FILI(I) CIVIS / SENONI ET CARSSO / UNAE CONIUGIS / EIUS ET QUINTI F(ILII)
and also a later Anglo-Saxon inscription recording the building of the church:
EIRTIG ME LET WIRCEAN / AND FIOS GODIAN / CRISTE TO / LOFE AND SANCTA / MARIE XP
This translates:
Eirtig had me built and endowed to the glory of Christ and St. Mary, XP
The Lacock tombstone, which rests on the beakhead corbels, came from St. Mark’s church (High St.) when it was demolished in the early 1970's. This raises the possibility that the corbels came from St. Mark’s as well.
