'One other set of notes is entitled ‘Remarques of Medls. How to know the true from the false,’ subsequently written in Italian. This does not, of course, mean they are derived from any book, although they recall the discussion of forgeries in Enea Vico’s Discorsi. As Courten does not give any source, they may well represent his own views. The notes cover topics such as how to recognise the ancient from the modern, how to recognise a fake patina, how forgeries would be made in bronze, how to tell an ancient die from a modern one, or how to assess the corrosion products.'
