Note 4 — Chapter II
Reading edition
The Doulting stone, of which the cathedral is built, comes from the St. Andrew's quarry at the little village of Doulting, where Bishop Ealdhelm died. It is inferior oolite, and very like Bath stone, which is the greater oolite. The exterior shafts were blue lias, and those within either blue lias or Purbeck marble, though there are one or two shafts of red Draycot stone in the western responds of the nave.
