Despite increasing dilapidation, many of Rome’s ancient buildings survived in a form to impress visitors. During the Middle Ages a number of them – Hildebert of Lavardin, Master Gregorius, Benjamin of Tudela – left a brief record of the favourable impression the ruins made upon them. More widespread, however, were the legendary accounts, as found most extensively in the Mirabilia Urbis Romae, of the history and function of a number of the ruins of the pagan past. Such fables can be seen as forerunners of later ruin-mindedness in their attempt to explain the original role in the urban fabric of what was now ruinous and puzzling.
