The Boslow inscribed stone in West Penwith stands at a crossroads of very ancient trackways – the overgrown one stretching away into the distance in the photo below is the Tinners’ Way, or Old St Ives Road, which is at least 4,000 years old and links St Just to St Ives 14 miles away and across the top of the Penwith Moors. It’s also right on the boundary of St Just and Sancreed parishes.
First mentioned in the Corpus of Early Christian Inscribed Stones of South-west Britain  `the stone was found in the summer of 1877 by G.B. Millett on the moor ‘under Carn Kenidjack’, the Cornwall Heritage Environment Record describes the stone thus:
An inscribed stone is marked at the location on current OS maps. It is situated in ‘Water Lane’ above Boslow and is on the parish boundary between Sancreed and St Just. On the front of the granite stone is an inscription ‘TAET VERA’ in two lines reading downward, and a peculiar cross with a looped transom. On the rear face is an incised cross (described by Macalister as a “cross potent”). The stone measures 4ft (1.22m) high and 1ft 2in (0.36m) by 1ft 1in (0.33m) wide. A site visit by the OS revealed that Macalister’s description of the stone appears correct. It stands on the north-east side of a small (probably modern) mound. The monument is included in the Schedule.
A 3D rendered model has recently been produced by Tom Goskar, and is available to view on the SketchFab site. The stone is thought to be in its original position at the head of a stone-lined grave and bears a single name which can only be read at midday when the sun is exactly in the south: TAETVERA. This is Latinised 7th century Cornish: Taithuere, “exalter of the journey”. The grave and mound have never been excavated and therefore provide one of the oldest known intact graves with a named occupant. A ground plan can be seen in issue 30 of Meyn Mamvro magazine, issue 30.
There has been some recent discussion of the stone on Facebook, where Cornish historian Craig Weatherhill supplied the following information:
A contemporary incised cross on the southern face of the stone, and Alpha-Omega symbols under the inscription, indicate that this is the grave of an early Celtic priest, but which one? “Taithuere” could be a “name taken in religion”, e.g. Wynfrith became St Boniface; Magonus was the birth name of St Patrick; and every Pope in history has done it, too.
Was there a local priest of this era who was known for taking himself off on frequent journeys? There was: St Just himself, actually a man called Yestin, who also journeyed to his other churches at St Just in Roseland and Gorran Haven, while there are tales of his visits to St Achebran at St Keverne. Then there’s the name of this stone in 1613: Crowze East (crows Ust, “St Just’s cross”). Is this the gravestone of St Just?
Yestin (St Just) was a son of King Gerent I of Dumnonia. His other two sons were Selyf (St Selevan), and Cado who succeeded him as king. Gerent I is known to have flourished at the end of the 6th century, so the mid 7th century date for the inscription on this stone would fit a son of Gerent perfectly. Selyf had a son Kybi (St Cuby, Tregony; also the St Kybi of Llangybi, Anglesey). Celibacy was not required of ordinary priests until the 12th century.
Sadly, it seems that the stone (and grave) is now in danger from modern farm machinery as a recent picture shows that deep rutted tracks have been made very close to, and over the grave.
Discussions with the landowner and Cornwall Archaeology Service are under way, and we can only hope that there will be a successful conclusion to those negotiations that will secure the future of the stone and grave.
