The ceiling in this room is ornately coffered. The mouldings of the coffers are enriched with a foliage design with multiple projecting tablet flowers. The coffer panels are textured and the entire ceiling painted white. Two new “period appropriate” chandeliers hang nearly centered on each the north and south halves of the room.
Ceiling ornamentation such as this is typically cast off-site rather than ran in place or hand carved on site. Specialty companies could produce the entire ceiling ornamentation and layout at their facility utilizing exact measurements of the room, disassemble the pieces, ship all of elements to the site, which were later installed by skilled craftsmen.

A table flower is similar to a rosette except it is typically a squared representation of an open flower with four main or large petals.
