The scaenae fons was divided into three superimposed orders, sitting upon a podium decorated with a figurative cycle dedicated to Apollo and Artemis. This building was erected in the third century AD during the reign of Septimus Severus, enveloping and cancelling an earlier theatre, perhaps of Flavian date. The theatre was used into late Roman times; an inscription dating to 352 AD cites the restoration of the scaenae fons.
At the time the higher levels of the decoration were waiting to be put in place, this is the lower region. There was restoration work going on, some of the sculpture on the scaenae fons had been installed, for others see my museum gallery.
