Attribution and other enquiries
After almost 40 years of responding carefully to every message about attribution and other enquiries, including many concerning supposed “secrets” hidden in Leonardo’s works, I am stepping aside from this aspect of my activity. As a professor, I have been committed to the notion of public service, and have not taken any money for opinions, but the quantity of material I receive and the abuse to which I am subsequently subject on the internet means that this ideal is no longer sustainable in the IT age. I am sorry. This is a pity, but my work as a historian in public is being seriously distorted, not least by the unnecessary personalisation of arguments about matters of judgement. I will continue to engage selectively with a few major items/issues and with important developments in the academic and public domains.
