This delightful Roman fresco of boats and fish now housed at Palazzo Massimo alle Terme dates to circa 125-150 AD and was discovered along thee Via Portuense near the ancient San Paolo River Port in Rome. The fragment shows marine life swimming alongside a small boat (which is repeated) or gala vessel being rowed through the water, while one figure rides astride a dolphin.
But, the story of its discovery is also very interesting and I’ll discuss that below. It involves Mussolini.
The fresco is celebrated for its fluid artistic execution and vibrant, naturalistic depiction of maritime life. It offers a rare, casual glimpse into the decorative preferences of Rome’s bustling merchant and riverside districts during the Pax Romana.
We can see the artist’s fluid brushwork, in which he utilized quick, confident brushstrokes characteristic of later Roman wall-painting styles. This approach prioritized motion and atmosphere over rigid realism, capturing the shimmering quality of water and life beneath it.
The artwork borrows heavily from xenia (paintings of hospitality gifts like food) and traditional marine iconography. However, instead of framing the animals statically, it integrates them into a lively, continuous underwater narrative.
The composition relies heavily on empty space to simulate the openness of the Tiber or possibly the open sea, layering multiple fish and a solitary rowboat across a light backdrop. The focal point is a sleek, long hull equipped with rows of oars. Known as a gala boat or festive vessel, it was typically used for river transport, celebrations, or religious pageantry along the Tiber. Multiple figures are subtly suggested as rowers. A gala vessel (or boat) refers to an ornately decorated ceremonial watercraft used for festivals, pageantry, and religious processions. Unlike practical Roman merchant ships used for heavy cargo or rowed warships designed for battle, gala vessels were built exclusively for public display, luxury transport, and celebrations along waterways like the Tiber River or deep volcanic lakes.
The surrounding waters are densely populated with anatomically identifiable Mediterranean sea life. Varieties of fish, including sea bass, sea bream, and mollusks, swim alongside the boat, showing the Romans’ deep familiarity with marine ecosystems. The “Tiber Illusion”: While the fish depicted are saltwater varieties, pairing them with a river-style transport boat highlights a popular artistic trope. Roman painters often created stylized, blended aquatic landscapes meant to evoke general abundance rather than exact biological geography.
Discovered at the San Paolo River Port along the Via Portuense, the painting did not originate from an imperial villa. Instead, it likely adorned a corporate office, a public building, or the private residence of a wealthy shipping magnate (navicularius) who managed the flow of goods into Rome.
Like many paintings preserved at Palazzo Massimo, this fragment was part of a larger trompe-l’œil wall design. It was meant to visually dissolve structural walls, opening up cramped, sun-baked brick interiors into refreshing, water-themed vistas.
But, there is even more to be fascinated by than the fresco itself. By that I mean that this fresco was discovered under the fascist regime of Benito Mussolini, specifically during the 1939-40 excavation at the Pietra Papa archaeological site, which was part of a major public works project to widen and clean the floodplains (golene) of the Tiber River. Mussolini was obsessed with ancient Rome, frequently using Roman history, symbols, and architecture to legitimize his fascist state. He funded massive excavation projects across Rome to unearth imperial relics and tie his regime to the glory of the Roman Empire.
The widening of the Tiber riverbanks where the villa was discovered served a dual purpose. It was a functional infrastructure project to control river flooding and, at the same time, an opportunity for state-backed archaeologists to search for ancient monuments. When workers stumbled upon the Roman villa and its nearby public bathhouses, the state’s archaeological authority (Soprintendenza) stepped in. They meticulously detached the fragile plaster frescoes to protect them from the river works, transferring them directly into the state museum system.
There are so many delights housed within the collections of this incredible museum complex. One after one, they are all delightful and expand our understanding of the varied artistic world of ancient Rome as well as the subsequent history of this fascinating country!
