Inscription engraved in the
proscaenium wall (wall sustaining the stage) of the theatre of the city of
Felicitas Iulia Olisipo. The text commemorates the reconstruction and decoration of the theatre's
proscaenium and
orchestra (semi-circular space in front of stage, where the illustrious members of the community would sit), financed by the
augustalis in perpetuity,
Caius Heius Primus, in 57 AD, during the principality of emperor Nero. The inscription ran across a single line along the whole
proscaenium, which consisted of several blocks of grey or lioz pink marble, forming rectangular and semi-circular niches. Of the 25 blocks with inscriptions recorded when the theatre ruins were discovered, in the 18
th century, only the location of nine are presently known, five of which are figured in the permanent exhibit of the Museum of Lisbon | Museum of the Roman Theatre.
