Perspective of a Dome on a Concave Octagonal Podium

Two studies, in section and elevation, for the gallery and upper stall front, and the base and pedestal of the columns. Implied scale, 2 inches to 1 ft (1:6).

Hawksmoor continued the mouldings of the cornice across the sheet in pencil and drew an incomplete reflected plan for the square soffit panel below these, 2 ft by 2 ft (with diagonal construction lines in the lower half). This is the soffit of an intended flat canopy above the Bishop's stall. At the next stage, he changed the canopy to an open-base segmental pediment, making the panel redundant. In anticipation of this chafe, he deleted to cornice on the present drawing in scribbled pencil and marked in heavier pencil a deeper supporting cornice carried on a large bracket. This bracket reaches down to the top of the stalls. It prefigures the winged-cherub brackets carved by Grinling Gibbons in the completed enclosure in 1695-97.

Below is a detail of the column bases and the remarkable curvilinear marble pedestals of the choir screen. They were executed close to this detail but with stylised water-lily leaves instead of acanthus on the angles, and with a separate acanthus scroll on the column plinth. Two pedestals survive with their columns in the internal porch of the south transept created by Penrose in the 1870s from salvaged features of the re-ordered choir enclosure (another on the north side was destroyed in 1941). The column base in this drawing is the enriched Corinthian version used for the main internal order. Two cavetto mouldings and a pair of tondino mouldings separate the upper and lower torus mouldings instead of the single large cavetto found in the plainer version of the Corinthian base used on the outside of the building. To the right, a small sketch marked 'D' shows the profile of the cornice of the marble pedestal concealed by the overlapping leaf moulding.
