Who was the artist Burney? According to the editor, Francesco Sastres, the figure of Mercury was drawn by James Barry after Raphael, and the composition as a whole was by "the very ingenious youth, Mr Charles Burney". Charles Rousseau Burney (1747-1819), a musician, was not a youth at the time, being aged 42, nor was his younger brother, the artist Edward Francisco Burney (1760-1848), being aged 29, nor was the schoolmaster and classical scholar Charles Burney (1757-1817), who was aged 32 at the time and not known as an artist. On the other hand the son of the schoolmaster, Charles Parr Burney, was an artist but was only born in 1785 so was no more than four years old at the time: if it was he, he was indeed "a very ingenious youth" and a child prodigy, and hardly to be described as "Mr.". The only alternative seems to be that Francesco Sastres gave the artist's forename as Charles in error for Edward Francisco, which also seems unlikely
