The artist appears to be unrecorded. The prototype by Nicodemo, who was active in Naples in 1780, is in an untraced private collection.
Nicodemo, now a forgotten master, must have been a not unobscure portrait painter in his time. He was befriended by Philipp Hackert, whose portrait by Nicodemo is now in the Staatlichen Museen, Berlin.
