In 1910, John Murray of London published The Mond Collection An Appreciation by Dr. John Paul Richter


In the late eighteenth century Dr. Mond had commissioned Richter to catalogue
his collection of works of art. This magnificent book was the result.
One of the paintings in the collection is below.

THE COLLECTION OF LUDWIG MOND F.R.S. London.
Dr Richter said about this work

"So many repetitions and variations of this composition by pupils of Leonardo exist that
it is reasonable to suppose that it is founded on a lost painting or cartoon by his hand."
