The volume publishes the results of the excavation conducted, in 2011-2012, at the baptistery of the Padua Cathedral. Although small in size, it provided very important data based on the sequence of three environments. Probably built in the XNUMXth century, they collapsed following a fire in the early XNUMXth century and were replaced by a couple of huts. After this phase, which at least marks a decline, if not an abandonment, of the episcopal center, between the XNUMXth and XNUMXth centuries, new monumental buildings referable to a baptistery and the cloister of the canons are being built again. These events are then framed in the history of the city, in crisis after the Lombard conquest, and of its places of worship, with particular reference to the suburban martyrial church of Santa Giustina. The excavation has returned a large amount of finds, both artifacts and eco-facts, from which further information on nutrition, the environment, and the physical characteristics of the buried, has been obtained, thanks to the involvement of numerous European specialists and laboratories who have applied the more innovative analytical methodologies. All this was possible with the financial support of the Cassa di Risparmio di Padova and Rovigo Foundation.
