Manius Acilius Glabrio
the construction of the sacred area of the forum dates back to the Republican age, more precisely to the period between the first and the second Punic War. Subsequently, at the time of Caesar (1st century BC), it underwent renovations which involved the demolition of a fourth temple: it was built by Manius Acilius Glabrio (consul in 191 BC) next to the Temple of Janus and was demolished during the construction of the Theatre of Marcellus (then completed by Augustus). The temple was dedicated to the worship of Diana.
