Preliminary design, and finished drawings for a ceiling for the Temple of Bacchus, 1761 (4)
Adam volume 54/1/52 has recently been attributed, and shows the early phase of the design for this ceiling.
In Adam volume 11/62 the original central octagonal panel has been cut away and the current drawing affixed.
According to King, twentieth-century excavations unearthed enough plaster fragments to show that there was a stucco ceiling in the Temple of Bacchus, though it is not possible to prove that this ceiling was to Adam's design. There are no known photographs of the interior.
