Beneath the
Indian Gallery and Central Dome and surrounding
Egeria's Fountain is the Central Hall. The columns are of "
Cintra's choicest stone, Blue marble". The arched recesses, that at some time contained statues, stand within pointed Gothic arches. These arches have an internal decoration of gothicised vegetation forming a pierced tympanum above a secondary circular arch. The spandrels are decorated with plaster reliefs that "
shine with leaf and bell Of Scotia's saucy emblem flower" (The Thistle) and above this there is a frieze of fruiting vines: "
And higher, fruit and foliage fine Betray the rich, the truant vine, Luxurient trailer !"
Medievalists regarded the thistle as a fine British substitute for the classicist acanthus.
Ruskin wrote in his Seven Lamps of Architecture a description of a gothic capital containing thistle decoration that could be applied to this spandrel: "four branches of thistle-leaves, whose stems, springing from the angles, bend outwards and fall back to the head, throwing their jaggy spines down upon the full light, forming two sharp quartre- foils."
