Turning to the corresponding arch on the south side of the presbytery, we find two tombs (Nos. 17 and 18). One (18) in Purbeck marble supports the figure of a bishop eucharistically vested and mitred, with a veiled pastoral staff in his left hand. The right hand is raised in benediction. Browne Willis conjectures[81] that this was the tomb of Bishop Gervase or Jorwerth (1215-1229), but later[82] he definitely states that it was unknown, but “_was unanimously assur’d to me to be the Monument of_ Bishop Jerworth.” It is possible that the figure (which is later than 1229) was placed over the remains of Gervase, during whose episcopate the present presbytery was largely erected. A pastoral staff (copper gilt) and part of its wooden stave, of a rich design, were found near here in 1844, and, Freeman notes[83] “is at present in the possession of the Bishop of S. David’s.” The other (No. 17) is to Bishop Anselm le Gras (1231-47), according to the inscription on the trefoiled canopy supported by angels and adorned with foliage: PETRA PRECOR DIC SIC ANSELMUS EPISCOPUS EST HIC. The Bishop is in relief and wears eucharistic vestments, with a rich mitre and pastoral staff unveiled but turned outwards, and the right hand is in the act of benediction. There is a kind of nimbus to the head and at the feet are two dogs, one of whom is pierced by the staff. Proceeding to the next arch further east immediately behind [Illustration: TOMB OF A KNIGHT AT THE BACK OF THE SEDILIA.] the sedilia, there is a recumbent figure in the armour of the late fourteenth century. This is attributed to Rhys ap Tewdwr, Prince of South Wales.[84] “The head, which has the conical basanet and camaille, is reclining upon a casque surmounted by the crest, _On a chapeau a lion sejant_. The body armour is covered by a jupon, on the breast and back of which are embroidered the wearer’s arms _[Gules,] within a bordure engrailed [or,] a lion rampant [of the second]_. It is not quite clear whether the jupon, which falls in a fringe round the hips, is meant to have sleeves, or whether the figure has a hauberk with short sleeves, those of the tunic appearing beneath them. The hands are clasped; there is a richly decorated belt and sword; the legs have complete plate armour, with genouillères; the feet have spurs, and rest on a lion.” In a corresponding position in the north choir aisle is another very similar tomb (No. 11), evidently of a member of the same family, probably by the same designer. The head lies on a double cushion, and the heraldic bearings on the jupon have a label of three points.[85] The general conclusion seems to be that these monuments are to Lord Rhys ap Tewdwr and his son Rhys Gryg. Before the restoration they stood under the same arches in the presbytery, not, as now, in the aisles.
