Inscription.
Costruiti come fronte scenografica del teatro giα in etΰ domizianea (fine I secolo d.C.), i due ninfei gemelli (A-B) presentavano una pianta semicircolare e furono inseriti in un piω tardo portichetto con colonne marmoree (C). Al ninfe Al ninfeo orientale nel IV-V secolo d.C. si sovrappose un oratorio (uno dei pochi edifici cristiani di Ostia), costituito da un vano con abside realizzato con muratura di reimpiego (D). L'oratorio fu eretto a memoria dei martiri ostiensi (tra cui S. Aurea e S. Ciriaco), che vennero uccisi nel 269 d.C. presso l'arco di Caracalla (E) costruito davanti al teatro: mantenne la propria funzione cultuale fino all'etΰ medievale, quando la cittΰ era ormai in completa rovina.
Built to adorn the front of the theatre already during the Domitianic period (late 1st century AD), the two twin nymphaea (A-B) had a semi-circular plan and were incorporated into a small later portico with marble columns (C). An oratory (one of Ostia's few Christian buildings) was installed in the east nymphaeum in the 4th-5th century AD, it consisted of a chamber with an apse and was made of reused bricks (D). The oratory was built to commemorate the martyrs of Ostia (including St Aurea and St Cyriacus), killed in AD 269 near the arch of Caracalla (E) that stands in front of the theatre. It maintained its religious function until the medieval period, when the town was already in ruins.

Excerpt: "To the south-east of the theatre are the scanty remains of a little Christian chapel, excavated in 1910 by Dante Vaglieri. The area in which it was built, marked E on the plan, had a long and complex history. Nymphaeum II,VII,7 (B) was a decorative feature from the first three centuries AD. Other constructions in the area (C, D) were razed to the ground. In the late fourth or early fifth century a roughly triangular area was created, flanked to the south by columns, to the west by the theatre, to the north by two columns (on of which is on top of a street), and to the east by block II,VI. The level of this area was raised considerably and covered with many small pieces of marble."(Submitted on August 9, 2025, by Sean P. Flynn of Oak Park, Illinois.)
