Today’s occasion takes me back 25 years when a number of interested colleagues and I tried to structure the syllabus for the MSt and MPhil in Byzantine Studies to include four auxiliary disciplines, namely Numismatics, Palaeography, Sigillography and Epigraphy. Numismatics was taken on by Michael Metcalf, Keeper of the Heberden Coin Room in the Ashmolean, and Palaeography by Nigel Wilson, while I was saddled with Sigillography and Epigraphy, on which I remember giving a number of lectures. That was in 1992.
