Apart from its position, however, the screen itself is not particularly noteworthy. The style is Decorated, verging towards Perpendicular. The upper part is open and filled with sexfoiled tracery, and the lower is, as usual, panelled. The centre is devoted to a wide entrance, and at different dates three others have been pierced. The =Stalls= are inscribed as follows:[32] SOUTH RETURN. NORTH RETURN. 1. Decanus. 15. Præcentor. 2. Archᵈ Meneue. 16. Archᵈ Brecon. 3. P. Llan Dewi. 17. P. S ᵗⁱ Nicholi. SOUTH SIDE. NORTH SIDE. 4. P. Cursalis. 18. P. Langan. 5. P. Treflodⁿ. 19. P. Cursalis. 6. ..... 20. .... 7. Vicʳ Episcop. 21. Succentor. 8. P. Cursalis. 22. P. Cursalis. 9. P. Cursalis. 23. P. Cursalis. 10. P. Cludeu. 24. P. Caer-Fai. 11. .... 25. .... 12. P. Caer-Farchell. 26. Archᵈ Cardigⁿ. 13. Archᵈ Carmarⁿ. 27. P. Aurea. 14. Cancellarius. 28. Thesaurarius. The constructional arches in the transepts are pointed throughout, with an occasional decorative circular arch, but are [Illustration: ARCH BETWEEN THE S. TRANSEPT AND THE CHOIR AISLE.] much plainer than those in the nave and choir. “The peculiar character of the more slender shafts has freer scope than in the nave and choir, where a more massive pier is employed; we may observe the general omission of the neck-moulding and the use of the ogee keel as at Llandaff. The latter is here applied very curiously, being, in several members, doubled and set laterally, the effect of which is by no means pleasing, though it may have had some influence on the architecture of the period.”[33] [Illustration: DOUBLE PISCINA, ST. THOMAS’S CHAPEL.] The transepts are approached from the nave--not, as is usual, through an open arch, but through original Transitional doorways. The wall which contains these doors effectually cuts off the view from the transept to the nave, and also serves somewhat to make the contrast between the elaborate nave and the rather bare transepts less marked. The =Chapel of St. Thomas the Martyr=, north of the north transept, and the buildings above form one of the many unique points of St. David’s. On reference to the ground-plan it will be seen that this remarkable building is placed at an unexpected angle, the reason for which is not apparent and remains unexplained.
