NOTES: Bonomi's design was based on the tomb of Caius Cestius, Rome. The mausoleum as executed in 1796 was a slightly less austere pyramid without the rusticated plinth.
NOTES: Perhaps a copy from a print of a design by a French architect. This drawing is found in an album which was formerly attributed to Sir William Chambers. It contains over 100 theoretical designs, mostly by Edward Stevens but with some by John Yenn and some from the office of William Chambers. Stevens was a pupil of Chambers from 1760 to 1766. The drawings in the album date from between 1762 and 1777.
