Le trappole della codifica. Osservazioni intorno ai sistemi di descrizione dei tipi di rigatura

The article offers a critical review of the various methods of classifications of ruling types, as elaborated by Kirsopp and Silva Lake, Julien Leroy, Agamemnon Tselikas, and Denis Muzerelle. Each classification draws on different principles and favours certain elements, but problems rise when ruling types need to be grouped and compared: these are highlighted and analyzed in the contribution. The discussion also focuses on general problems involved with the use of classification systems to describe complex layouts, especially those found in glossed manuscripts.
