The theatre was built along the Decumanus Maximus. The
outline could already be drawn in the early 19th century.
The excavation was completed in the years 1880-1881,
1890, and in the early 20th century. The building was
restored very extensively.
-
- Fragments of an
inscription tell us that a first theatre was built at the
end of the first century BC by Agrippa, the right-hand of
Augustus (opus reticulatum and large tufa blocks). It
could hold 3000 spectators. It
was built together with a large square to the
north,
the
Piazzale delle Corporazioni
(II,VII,4).
-
- A
large inscription from 196
AD (originally
bronze letters inserted in a marble slab) tells us that
the theatre was re-dedicated by Septimius Severus and
Caracalla. Brick stamps however show that this complete
rebuilding had been started by Commodus (176-192 AD).
The
theatre could now hold 4000
people.
-
- The
new theatre was made of
brick. The facade
is turned towards the street. In front are two nymphaea
(II,VII,6-7). This area had a travertine pavement and was
surrounded by travertine piers, between which were
chains. In
the facade are sixteen
shops with back
rooms. Some shops had simple wall-paintings. They were
behind a portico, entered through arches. Between the
arches were brick pilasters with travertine bases.
There
were also arches on the second and third level (on the
highest level with
windows).
-
- The lower level of the
seating area (cavea) could be entered from the Decumanus
through a central
corridor, and
through two lateral entrances. The entrance in the centre
of the shops had a pavement and wall revetment of marble.
The vault was decorated with stucco reliefs. Four
staircases between the shops led to the second and third
level. The seating area could be shaded by an awning,
suspended from poles inserted in travertine blocks. The
seats themselves were probably covered with marble. On
the third level were marble
columns (now
re-erected behind the stage).
-
- The area in front of the
seating area (orchestra)
had a marble floor. In
the front of the stage
are five semicircular and four rectangular niches,
decorated with marble, including a cornice and small
columns. Holes in the stage were used to fasten the
scenery. The back wall of the stage has disappeared
almost completely. On the stage some marble
theatrical masks
can now be seen, that once decorated the building.
-
- One ancient text
probably refers to the Ostian theatre. In 197 AD
Septimius Severus addressed the Senate in Rome and said:
"For if it was disgraceful for him [Commodus]
with his own hands to slay wild beasts, yet at Ostia only
the other day one of your number, an old man who had been
consul, was publicly sporting with a prostitute who
imitated a leopard" (translation Loeb, E. Cary).
-
- At the end of the fourth
century AD the building was restored by a prefect of the
grain-supply, Ragonius Vincentius Celsus. A statue of
Roma was erected outside the theatre. The orchestra and
the stage were connected through steps in two of the
rectangular niches in the front of the stage. In the
central corridor benches and an arch were built with
bases from the Piazzale (the square was no longer being
used for commercial purposes). The south part of the
central entrance corridor and the two flanking shops with
back rooms were blocked and converted to cisterns, with
hydraulic mortar (opus signinum). The orchestra could now
be flooded for aquatic displays. The water reached the
orchestra through two holes in the side walls of the
northern part of the corridor. The pool was not very
deep: 1.40 meters at most. Naval battles were of course
not re-enacted. We should imagine a choreography of the
gods and goddesses of the sea and lakes, of nymphs and
nereids, presumably scarcely dressed.
-
- At a later point in time
the arches of the first level were blocked, so that the
building could be used as a fortress. This may have been
done in the fifth or sixth century, when Goths and others
invaded Ostia and especially Portus.
