Terme del Foro
⎯⎯⎯
Baths of the Forum
(Reg. I, Is. XII, 6)
Costruite intorno al 160 d.C. da Marco Gavio Massimo, prefetto del pretorio di Antonino Pio, queste sontuose terme pubbliche (le piω grandi della cittΰ) subirono importanti rifacimenti nel IV e nel V secolo d.C., tra cui la creazione di un ingresso monumentale su Via della Forica (A). Attraverso i vestiboli (B), si raggiungevano gli apodyteria (spogliatoi) (C) e un grande frigidarium (sala con vasche per bagni freddi) (D) con alte volte a crociera. Le sale riscaldate erano rivolte verso sud, in modo da sfruttare al meglio l'esposizione ai raggi del sole: il primo ambiente, di forma ottagonale, era probabilmente un eliocamino (sala dedicata ai bagni di sole) (E); seguivano un laconicum (sala per bagni di sudore) (F) e ambienti tiepidi (G) e caldi (H). La ricca decorazione marmorea dell'edificio risale ai restauri del IV secolo d.C.
Built in around AD 160 by Marcus Gavius Maximus, the praetorian prefect of Antoninus Pius, these luxurious public baths (the city's largest) underwent significant renovations in the 4th and 5th centuries AD, including the construction of a monumental entrance on Via della Forica (A). Through the vestibules (B), patrons entered the apodyteria (changing rooms) (C) and a large frigidarium (room with basins for cold baths) (D) with high cross vaults. The heated rooms faced south to best exploit their exposure to sunlight: the first room, octagonal in shape, was probably a heliocaminus (room for sunbathing) (E); it was followed by a laconicum (room for steam baths) (F) and warm (G) and hot rooms (H). The building's rich marble decoration belongs to the restorations of the 4th century AD.

Excerpt: "To the south-east of the Forum is one of the largest baths in Ostia, the Baths of the Forum. The total area is c. 3200 square meters. The building was plundered in the early 19th century and probably at other moments. The final excavation took place during a long period, in the years 1920-1941. Some minor work was carried out in 1959 and 1980.(Submitted on August 12, 2025, by Sean P. Flynn of Oak Park, Illinois.)
Several phases can be distinguished, on the basis of inscriptions and brick stamps. All masonry is opus latericium, with the exception of the last phase, which also has some opus vittatum.
The baths were built in the third quarter of the second century, c. 160 AD, by Marcus Gavius Maximus, praefectus praetorio.
Early-Severan period (193-225 AD).
Reign of Maxentius and Constantine (306-337 AD; possibly two phases).
Restorations financed by Flavius Octavius Victor, praefectus annonae at some point in time after 331 AD (possibly the same as the Constantinian phase).
Reign of Theodosius (379-395 AD), probably financed by Ragonius Vincentius Celsus, praefectus annonae in the years 385-389 AD."
